GEAR

This gear list is meant to help anybody who signed up for the YAU or is interested in participating. It will help you getting an idea of what is needed.

Products that have been tried, tested and really work well in the Yukon winter get 6 stars (******). Prices often change with every season. So, my apologies if the recommended retail prices sometimes are not up to date.

Please keep in mind that a list or other input can never cater to the needs of every racer. What may work wonders for one athlete may be absolutely useless for the next. It remains your responsibility to have the gear that is right for you.

Last but not least, the below list is not complete. There will be kit, clothing or other items you need/want that are not on this list.

From May 2026 onwards I will update the list, step by step. I will leave the original gear list online unitl I have updated all topics. The updated sections will be marked be the word “NEW!”

Clothing – 1st layer (NEW!)

You have plenty of options for your 1st layer, but the priorities are always the same: comfort, freedom of movement, and moisture management over long durations. You’ll try to manage your effort and layers to avoid sweating, but it won’t always work 100%. When it happens, you want a base layer that moves moisture away from your skin and dries quickly.

1st layers range from very thin to more insulating options. The right choice depends on the conditions, how you personally handle the cold, and how the piece integrates into your overall layering system.

A higher percentage of merino wool can help manage odor. That said, merino isn’t for everyone – make sure your skin tolerates it over extended wear. I like merino, but over time it dries out my skin and becomes itchy. It also doesn’t always move moisture as efficiently as synthetics. While it retains warmth when wet, running for hours in a damp layer isn’t ideal. That’s why many brands blend merino with synthetic fibers to balance comfort and performance.

Winter running tights aren’t listed below, but they can work well as a base layer. In milder conditions, they may be all you need for your legs. Just be careful with wind exposure – non-windproof tights can become a liability. You may not immediately notice it, but sustained exposure to cold wind can increase the risk of frostbite.

Other things to consider:

Does the shirt have a zip collar with a metal puller? If so, does the puller come into contact with your skin (= potential for frostbite)?
How does your base layer interact with your other layers?
What’s your drop bag strategy – what are you carrying, and what are you planning to swap out later in the race?

Thin longsleeve shirt with zip neck	I really liked Montane’s Primino range. It was 50% merino wool yarns, combined with 25% PrimaLoft® and 25% Polyester. My favourite version was 140 g/m² – a rather thin layer but surprisingly warm. The combination of fabrics worked really well and tried to find the middle ground between the positive effects of merino wool and improved moisture management and durability with high quality Polyester. So, that’s what I would be looking for: a thin 1st layer that features merino wool but also synthetic fibres for the best of both worlds. An example would be the Woolpower Zip Turtleneck LITE. If you can’t wear merino wool, you could pick light and functional winter underwear from your favourite brand – most brands will have something like this in their range. It definitely makes sense to go with a product that does feature Polygiene®-treatment – to help prevent odor.	220 g (size M)
Medium weight longsleeve shirt with zip neck	This is one step up in warmth. Some brands would call this “thermal” underwear. Again, you may find something with a certain content of merino if you like. The weight should be around 200 g/m². I am a big fan of the Woolpower Zip Turtleneck 200. There is a reason why this product is basically the same ever since it was invented. It simply can’t be improved. Again, if you can’t wear merino, there are plenty of alternatives that are 100% synthetic. And of course there are many brands making this category of underwear with merino.	250 g (size M)
Thick longsleeve shirt with zip neck	This category crosses over into the 2nd layer. A great material is Polartec® PowerStretch® Pro™, e.g. the Warmpeace Fram Pullover. You could wear it next to skin as a really warm 1st layer but also as a 2nd layer over a thinner shirt. The nice thing about Polartec® is that it is very warm, super comfortable, moves moisture away efficiently, dries quickly and is light.	320 g (size M)
Thin long johns	This is a reflection of the shirt. For the sake of having a weight, I will go with the Woolpower Long Johns LITE.	195 g (size M)
Medium weight long johns	Same as above. So, let’s go with the Woolpower Long Johns 200.	200 g (size M)
Thick long johns	I will go with the Warmpeace Fram Pants. Like the shirt, it is made from Polartec® PowerStretch® Pro™.	250 g (size M)

Other options / Things to consider

There is too much product on the market for me to be certain I am not forgetting anything interesting.

One brand that I really like is X-BIONIC. They have an incredible amount of features in their first layers the moisture management is excellent. It’s an interesting option for anyone who can’t use merino wool or wants to complement merino layers with something 100% synthetic.

Another type of product that seems to be on the rise is underwear of things that I have tried are with netting (e.g. Aclima WoolNet). The idea is that is saves weight but does not compromise on insulation because the trapped air also keeps warm. And of course it breathes well and dries quicker.

Saving weight

When it comes to saving weight with 1st layers, the question is not so much about what fabric to use. You will definitely want a thin and a medium weight 1st layer. A thicker layer of Polartec® PowerStretch® Pro™ or similar is also good to have. It’s more about how many sets of underwear you want to take … Ideally, you use your drop bag well for this, i.e. obviously don’t carry the underwear for the entire race with you if you can deposit some in your drop bag. The rest is personal preference. If your sled ends up being too heavy, the quantity of underwear you have with you is something you can re-visit.

Clothing – 2nd layer (NEW!)

Again, there are many options. Some of the above below be worn on top of underwear or over a 2nd layer and thus be turned into a 3rd layer.

The main focus of your 2nd layer will likely be additional warmth. Windproofness may not be relevant, yet. However, there are plenty of 2nd layers which already keep the wind out.

Breathability is still very important and you want something that transports moisture on to the next layer. Synthetic fills like PrimaLoft® are very popular as they are warm, pack down well, are light, robust and easy to handle (there is no down that can clump) and no pilling of any surfaces.

Thin down jackets or tops are an option for those who have an absolute focus on ligth weight. No synthetic fill can beat down on warmth to weight ratio. Just make sure you get high quality treated down as it will handle moisture a lot better.

If you like natural fibres, merino remains an option, too. Woolpowers 400 and 600 g ranges are pretty amazing. Just pack size and weight are not as good.

Thin fleece jacket or top	This could be something made of Polartec® PowerStretch® Pro™, i.e. thin, close fit and perfect for moisture transport. Of course there are also plenty of fabrics with the same features that are not Polartec®. It’s a matter of personal preference if you want something with a high colar and more a jacket style with a full-lenght zip or something with a 1/2 or 3/4 lenght front zip. Obviously, the advantage of the zip is better temperature control. An example would be the Montane Fury Lite Fleece Jacket (290 g), made out of THERMO STRETCH. Another type of fleece that works well as a second layer is Polartec® Power Grid™. As Polartec® puts it: “… designed to optimize and regulate body temperature. The proprietary grid fabric construction bi-component knit wicks away moisture and transfers it to outer layers for fast evaporation. It’s grid design creates open air channels to increase breathability and reduce bulk, while enhancing thermoregulation. A reference product would be the Montane Protium Lite Pull On Fleece (200 g) – which is not Polartec® but THERMO GRID.	200 – 300 g (size M)
Medium to thick fleece jacket	When we move on from the thinner to the thicker fleece layers you have an incredible choice of materials, styles and features. The focus remains additional warmth and breathability. Some fabrics, are high-pile, like Montane’s THERMO HL or Polartec® High Loft™ have a structure that will trap air and thus the weight to warmth ratio is really good. Also, these materials are super comfy and will dry quickly. If we take the Montane Caldus XT Hooded Fleece Jacket as an example, we are looking at a weight of 490 g. Often these jackets are hybrid, i.e. combine different types of fabrics to improve the performance of the product. They might have patches of windroof fabric in the chest area and/or a more breathable fabric on the sides and/or robust fabric in areas of “wear and tear”. Lighter fleece jackets with less “fancy” stuff, like the Revolution Race Hiker Full-zip Fleece will be around 300 g in weight.	300 – 600 g (size M)
Synthetic fill top or jacket	In this category ther is some surprisingly light product. Still the warmth you will get from a layer like this is really good. Another big “pro” is the small pack size and the fast drying. The Montane Fortes Nano Insulated Half-Zip Jacket only weighs 210 g. Their Sirocco Hooded Insulated Jacket with a full front zip and hood is about 350 g. A further advantage of these types of jackets is that the outer fabric will often be windproof or wind resistant. So, should the wind pick up you may not immediately need a layer on top. Of course, the more weather resistant the outer fabric is the less it will breathe. Most brands will have something like this in their range. And, just with the above fleece jackets, the construction can also be hybrid, e.g. integrating fleece or different outer fabrics in the construction.	200 – 400 g (size M)
Down filled tops	Down as a 2nd layer can be tricky. Even if the down is treated, it won’t work as well when wet. So, using it would only make sense if you hit that sweet spot of needing the warmth but you won’t start sweating. The one thing that makes it interesting to consider is of course weight and pack size. Both will be really good for the amount of warmth you get. Plus, you can of course use it as a 3rd layer. Not many brands make actual down tops. Cumulus is an exception. They have the Plancklite Down Pullover that only weighs 130 g (!). Their Primelite Pullover at 190 g is also very interesting. There of course are light down jackets you could wear as a 2nd layer but I will put those in the category “additional insulation” further below.	130 – 200 g (size M)
(Merino) wool tops or jackets	If you are a big fan of (merino) wool you may have or want to consider that material for a 2nd layer, too. When it comes to sustainability and the natural properties of the material, it is a good choice. The issue with the 2nd layer will be weight. For example, the Woolpower Full Zip Jacket 400 weighs 570 g.	570 g (size M)

Other options / Things to consider

In general, for your choice of layers you need to consider if you are someone who sweats quickly and/or you do get cold easily. If you sweat easily, you will have to manage your layers well and focus breathability. If you get cold quickly, you want to make sure you do have some really warm options.

While some 1st layers may not have a zip, the 2nd layers will. Make sure all your clothing features high quality zippers, e.g. YKK. Many cheap brands or product uses zippers of lesser quality. While that may not be much of an issue when used in a warm climate, it can really be a pain in the cold.

Also, when it comes to durability, should you be wearing your pulk harness over the 2nd layer, beware that there will likely be abrasion. The weaker the outer fabric, the more abrasion you will get.

Since a few years, the outdoor industry has put more emphasis on sustainability. By now there are a lot of materials with high or 100% recycling content. If you are buying products with synthetic fabrics, it’s worth checking if you can get something that is recycled.

Saving weight

The situation is similar to what you are dealing with regarding your 1st layers. It is still more about how many and not so much about what type of layers you have in your sled.

One way to save weight is by steering away from heavy merino wool products. Another option is to complement the fleece jackets you have with something that uses a synthetic fill or maybe even down. Especially the thick fleece jackets can be quite heavy …

Clothing 3rd layer/insulation (NEW!)

You likely will need a third and insulated layer to move when it gets very cold. Of course there are thinner insulated layers for less extreme temperatures and warmer ones when we reach – 20°C, -30°C, -40°C or colder.

Some insulation you will need when you stop to melt snow, prepare a meal, need to repair something, etc. You are not moving, your body does not generate heat and you need this clothing to stay warm. This also means that there is potential trouble if you are moving and you already are wearing your warmest jacket and pants.

When chosing your warmest clothing please also keep in mind that with fatigue and exhaustion your body will need more insulation than it normally would.

You may also need this equipment when temperatures go down to extremes in order to get a bit more insulation in your sleeping system.

Do not underestimate emergencies. You may plan to avoid staying out in the cold without moving. However, circumstances may force you to do it. You may encounter another athlete you need to help, you may not find the trail due to fresh snow or may have a problem yourself.

Thin jacket with synthetic insulation	Let’s start with a thin layer of synthetic insulation, like the Rab Xenair Alpine Flex Insulated Jacket. For that, Rab have combined “PrimaLoft® Gold Active+ insulation, which breathes and insulates through peaks and troughs of activity, with low-bulk Thermic™ stretch fleece side panels that offer superb mobility and make the jacket easy to layer”.	354 g (size M)
Thick jacket with synthetic insulation	There is of course also a category in between the thin and the thick insulation – basically anything that is in between the two weight classes. You may also prefer to have a medium weight and a warmer layer rather than a thin one. Basically, this jacket, in combination with layers underneath, should be warm enough while moving down to the extreme temperatures. Stayin in Rab’s product range, the Cirrus Ultra Insulated Hooded Jacket is an interesting choice. “The Cirrus Ultra takes synthetic performance to the next level, offering exceptional warmth for weight. It’s filled with new PrimaLoft® ThermoPlume®+ loose fill insulation, which closely mimics the lofting capabilities of down while expertly dealing with damp, cold weather. Boosted with heat-reflective TILT and body-mapped sheet insulation that stands up to moisture and rigorous use, it offers you instant warmth and comfort in any conditions. Durable, packable, and loaded with storage …”.	548 g (size M)
Thin down jacket	Another way to get insulation is a down jacket. Since you may use this layer a lot, the obvious challenge is to avoid sweating. That’s always important but with down clothing it is paramount. Treated down handles moisture better but it has its limitations. However, when it comes to getting great warmth, with low weight and small pack size, down is incredible. The Cumulus Inverse Jacket for example is in the category of very light down jackets. It features high quality materials and filling at a weight of 230 g.	230 g (size M)
Thick down jacket	Similar to above, I will jump right to the warmer down jackets. You have one million choices for a jacket between the two “extremes”. Mind you, this still is not your expedition down jacket! It is tricky to use a thick down jacket while on the move. Again, mainly because of the risk of sweating and not being able to use it when you most need it. The Rab Glaceon Pro Down Jacket is in this category. It uses 265 g (size M) of 700FP recycled down with Nikwax fluorocarbon-free hydrophobic finish.	584 g (size M)
Expedition down jacket	This is the jacket that is specified by the rules. It is your lifeline when things become extreme and/or whenever you come to a stop and need to stay warm. It can also help you beef up your sleeping bag with extra warmth. You should not need it when you are on the move. If you do use it as you are moving, DO NOT SWEAT into it! Most brands that cater to high altitude mountaineering have a jacket in this category. If you do not want to buy one, you can rent it from us. We use the Montane Apex 8000. It has got 500 g of high quality down fill and many useful features. NOTE: Down fill is not fill power! Down fill refers to how much the down weighs that is in the jacket. Fill power is an indicator how well the down lofts. So, if you get a down jacket with 800 fill power it is not necessarily warm enough! If you have an expedition down jacket and you are not sure if it’s warm enough or if you want to buy one and you have doubts, please ask! I will let you know if it would pass the gear check.	1,455 g (size M)
Insulated Pants	As is the case with the upper body, you have the choice of down or synthetic insulation for your pants. The Cumulus Basic Down pants weigh 185 g (size M). However, it does not fit a zip that would allow you to put it on without taking your shoes off. The Rab Photon Insulated Pant uses PrimaLoft® Gold and weighs 547 g (size M). It does feature a size zip to put it on and take it off easily.	185 g (size M)
Insulated short/skirt	I really like insulated shorts – often used for ski touring. It gives me warmth where I need it and allows for a lot of breathability. The Warmpeace Rond Short for example weighs 180 g (size M). The equivalent for women are the insulated skirts.	180 g (size M)

Other options / Things to consider

So, once again, many options. In the end, it’s one of those things that you will simply have to try out. You will decide for certain products/combinations and only the race will show you if it works as you expected it. Likely, over the years you will come up with your system and replace something that you initially thought you would like but you found a better solution.

Saving weight

I would recommend to combine down-filled products with synthetic ones. To go 100% down is only a good idea if you have tried it and know you can manage your layers so well that the down won’t get too wet.

Obviously, it is also about quantity. Jackets can weigh quite a bit and it’s not a good idea to take too many jackets … Below I am also giving you a tipp for a very special product that may help you save weight.

Montane Extreme Smock

The Extreme Smock was the reasons why I got in touch with Montane 20+ years ago. It was one of the earliest pieces of kit this British brand had launched and it was a key piece to their early success.

The DRYACTIV 3000 deep pile lining provides exceptional warmth and moisture management. Add to that a windproof outer, removable hood, large kangaroo chest pocket, incredible ventilation and a number of other features and you have a the perfect smock for extreme winter adventures.

Weighing 965 g (size M) it is not the lightest layer. However, you can practically live in it. The fleece will adjust to your body like “memory foam”. It will become your armour and for most it works down to incredibly low temperatures – if you are on the move.

For a couple of years Montane removed the Extreme Smock from their range but last winter it made it back – I am guessing, due to high demand.

The image on the right shows Thierry Corbarieu at the YAU 2019, using a Montane Extreme Smock and winning the 430 mile distance – captured by markkellyphoto.com.

Should you not be able to get one your size or want to look at alternatives, there is also Buffalo, making products with the same idea, i.e. windproof outer and deep pile liner.

I still have some Montane Extreme Smocks and Jackets in stock, too. If you are interested, please get in touch.

Clothing – 3rd layer/shell (NEW!)

The third layer has to protect you in the harshest of conditions when you are still on the move and your body generates heat. Normally this means you are looking for something that keeps the wind and snow out.

The more breathable the layer, the better. Jackets with less breathability usually feature pit zips which help with temperature regulation.

If you can put on and take off your third layer pants without taking your shoes off it will be a lot more convenient for you.

As always keep in mind how your layers work together and think about the options you have. Sometimes your third layer can of course also be used above your first layer, e.g. you are perfectly fine with your first layer (winter running tight and thin fleece) but on a lake crossing it gets a bit windy and cold. Here you may just opt for putting on your windproof pants and jacket.

The lighter you go, the less robust your clothing will be. And lightweight may result in better breathability but it may also be the total opposite. Check out the water column und breathability (so called MVTR) if the manufacturer states these values.

Never forget: no matter how many layers you wear, try to avoid sweating! And if your third layer is wind- and waterproof it may not be as breathable. Then you need to take it off in time. Otherwise, your clothing will freeze on you as temperatures drop and you will be in big trouble before you know it. This is even more so important if you don’t carry any more spare clothing in your sled or on your bike.

Waterproof pants

Some years ago I would have said that waterproof pants are not needed or don’t make much sense. We used to hardly get any snow and if so it would be very dry. Now we can get snow and it can be wet snow – even rain is a possibillity. We have not seen rain during the race but there was one winter that had a couple of days of rain just before we started.

Also, fabrics have been getting more and more breathable, light and often waterproof pants have zips along the sides for ventilation. So, if you do take waterproof pants, that’s what you want, a light fabric, ventilation on the sides and a zip that allows you to put the pants on and take these off, without having to take off your shoes.

Of course these pants also need to fit over your 1st and 2nd layers and be robust enough for winter use – in other words your lightweight waterproof pants for trail running may not do the trick.

As a reference product, we can pick the Rab Downpour Mountain Waterproof pants. A hydrostatic head of 20,000 mm is sufficient and the MVTR of 20,000g/m²/24 hrs is good. The 40D Pertex® Shield 2.5-Layer fabric offers enough robustness.

271 g
(size M)

Waterproof jacket

The factors to consider the waterproof jacket are very similar to the pants. You want light but still robust and large enough to fit over other layers – including down jacket. No matter how breathable the jacket is on paper, pit zips are useful because in a waterproof you will start sweating sooner or later.

If you wear your harness over the jacket there is a good chance there will be some abrasion. The problem is if you want to avoid that with a reinforced GORE-TEX® Pro- type jacket, not only are these very expensive but usually also on the heavy side.

Somewhere between those two “extremes” is a jacket like the Montane
Torren Waterproof Jacket. It is very breathable, has got a hydrostatic head of 20,000 mm and is robust enough; plus it features pit zips.

425 g
(size M)

Other options / Things to consider

If you do go for a windproof instead of a waterproof, that is of course acceptable. But then you should have a back-up solution if the windproof layers get to their limit – maybe an ultralight waterproof poncho?

Obviously, you can make your choice also dependent on the weather forecast, e.g. great weather for all of your race means winproof may be enough. Or great weather at the beginning may mean you can put your waterproof layers in the drop bag and you start with windproof instead.

Softshells usually are comfortable and breathable, while still offering good weather protection. All very useful when being out all day. However, softshell might be heavier than other solutions …

Saving weight

If your sled weight is too high, the 3rd layers may play a role in it and give you some possibilities to improve. As is the case with any equipment, going very light will come with drawbacks. #1 Less features. Less weight may be achieved by no zip or a shorter zip, no pockets and so on. And that may be totally fine but is worth keeping an eyon on. #2 Less robustness. Some light fabrics still are pretty robust but obviously a heavy duty fabric, maybe even with some reinforcements, will last a lot longer than thinner and lighter fabrics.

Advice on gloves

In order to survive in extremely cold conditions you need warm, functioning hands. This goes especially for emergencies. If you need to build a fire and or light your stove and your fingers are frozen your chances to get through the situation without major problems are very slim.
Rather one glove or mitt too many than not enough!
Even with really good mitts it may happen that your fingers get cold. Chemical heat pads, which many places in Whitehorse sell, may help. But be careful if too hot these heat pads may cause other problems.
Always know where your gloves are. Secure your warmest mitts with a string to your jacket. After a bivouac or other breaks, make sure you do not leave behind your gloves.
If you bivvy take the gloves with you inside the sleeping bag.
Be careful when you are trying to dry your gloves (or any clothing for that matter) over an open fire.

Clothing – gaiters

Kahtoola LEVAgaiter Tall GTX

extremely light, packable gaiter constructed form GORE-TEX®

also available in a Mid version

130 g
(size M)

******

Advice on gaiters:

Gaiters are not a must as we should never get massive amounts of fresh snow. But even with a bit of fresh snow and drifting snow on lakes or rivers it can be nice to keep the snow out of your shoes that way. Or maybe you want to bivvy off the trail and the snow is deeper there.
In extreme conditions gaiters also bring a bit of insulation.
Breathability is useful and make sure you test the gaiters with your (trail running) shoes. Maybe your gaiters work great on boots but they do not really work with the shoes you use in the Yukon.

Clothing head/neck

Montane Punk Balaclava	interesting combination of DRYACTIV Stretch fleece fabric and windproof PERTEX® QUANTUM enhanced nose ventilation mesh panel around the mouth mini peak Visor slit	60 g (one size)	€ 40.00	******

Advice on head/neck:

What’s missing here are neck gaiter, sun glasses and ski goggles. The latter you will need if the weather is so cold/bad that all of your facial skin needs to be covered.
The head is important for the temperature regulation of your body. So, be careful not to lose your hat(s).
You need a functioning solution for the worst conditions and the real cold. Which is a challenge because as soon as you cover your mouth and nose with fabric you will start creating an ice mask, even if there are holes for breathing in the fabric. And there is not much you can do against it apart from taking the ice off or in case of the neck gaiter to keep turning it.
If you wear glasses things become even more difficult. These fog up really easily when using a neck gaiter or balaclava. Day lenses may be a solution.
Problem areas are nose and cheek. You may not feel too cold but your nose and cheek already have a frostbite. And frostbite means your race is over even though you otherwise feel great. There is special tape on the market (Frost Tape) and some people even just use duct tape. Not sure what dermatologists would say about that though …
ColdAvenger masks also seem to work quite well for some people.

Clothing – socks

Woolpower Socks 200	socks with merino – warm and keep the bad smell away also available in a warmer 400 quality		€ 18.00	******
SealSkinz Cold Weather Mid Length	waterproof 3-layer socks with merino inside please note that breathability is limited – which is great if it is extremely cold as your feet do not get cold. But when it warms up your feet may start sweating, eventually causing bad blisters. Therefore, only use when you otherwise can’t keep your feet warm different levels of insulation available (also “Extreme Cold Weather Mid Length“)	142 g (size L)	€ 49.95	******

Advice on socks:

No matter what socks you go for, make sure you test as much as possible.
While moving and in “normal” temperatures a warm running sock (no examples above) may be all you need.
When it gets really cold or when you stop moving you will likely need more warmth.
The waterproof SealSkinz are not a must but these sure have worked well for a lot of participants. If you get some test as much as you can. The fit is good but not comparable to that of a regular sports sock. So, you may want to wear running or liner socks underneath. In any case it’s a thick layer and may even influence your choice of shoe size.

First Aid

LIFESYSTEMS Light and Dry Pro First Aid Kit	light, comprehensive packed waterproof	156 g	€ 24.95
Spenco Blister Kit	for blister prevention and treatment	20 g	€ 14.95	******
ACME Pfeife Tornado 2000	probably the world’s loudest whistle	10 g	€ 8.50

Advise on first aid

Instead of buying a complete first aid kit which contains things you do not want you can of course also go by your experience and get what you really need.
You should spend some time and think about what it is you really need or how the cold impacts the contents. Maybe certain things need to be close to your body heat or warmed up to work? If in doubt as your doctor or a pharmacist.
Like in most ultras blisters are a problem at the MYAU. Ideally you do something about it before it gets bad. If you do not know it already, find out how to prevent and treat blisters.
We do have a medical team at the MYAU and they are happy to help. But they may be busy dealing with an emergency and have no time to treat every little blister. So, please be prepared to deal with less compliated medical problems (and blisters are in that category) yourself. That goes even more so for when you are between checkpoints.
It makes sense to have your first aid kit in a waterproof bag.
First aid may also mean that you need to build a wood fire really quickly. Therefore, you should have different fire starters and means to light a fire with you. And it makes sense to pack these in different places.

Advice on skin care:

If you have the right clothing you have already done a lot for your skin care. But as is the case with any ultra, there are bound to be problems, e.g. with your feet or the harness of your sled. No matter what skin problem it’s good if you have what it takes to prevent or solve it. Or at least control it.
Lotions can help but beware that if you leave it in your sled it will freeze on you.

Advice on cooking:

Some try to avoid using a stove whilst others really enjoy the break and getting something hot to drink in between. But even if you do not plan on using your stove you need to know how to handle it and possibly repair it.
If you have not used your liquid fuel stove in a while please test it before you leave for the Yukon. It may need some cleaning or maintenance.
Keep in mind that ideally you can keep on a thin glove while lighting your stove. If you can’t have a glove on, you have to be super quick when it’s really cold out.
While gas stoves are easier to handle these will not work reliably below – 20° degrees. Therefore, according to the rules these are not allowed.
Alcohol stoves fairly easy to light and pretty reliable. However, they are not efficient when it comes to melting larger volumes of water. Therefore, just like the gas stoves, these are only allowed as a back-up solution.
It’s hard to say if transporting a multi-fuel stove will get you in trouble at the airport. Of course you have to clean it really well. The slightest smell of gasoline and they won’t let you take it. But I have heard so many stories of how it was no problem for some and others were allowed to take the bottle but not the stove and vice versa.
You do not need titanium pots and cups which are the most expensive. I just like them because they are light. But for functionality other materials are just as fine.
At the MYAU we rent out the Primus OmniLite Ti and MSR XGK if you don’t want to worry about transport or buy a stove.

Advice on sleds:

For those not on MTB the sleds is a vital part of your kit. If you want to save some money you can of course improvise and build your own hauling shafts and harness, use our own duffle bags, etc. Just make sure you really test your set-up back home. It can become a bit stressful having to deal with sled problems last mintute.
Every now and then participants prefer rope for pulling the sled. It’s really up to the individual. I personally prefer hauling shafts because of stability and the easier handling on downhills.
Be prepared for repairs. Your sled or parts of it may break or come apart. Think about possible problems and make plans how you would solve them. Do you need special tools? Spare parts? Screws and bolts?
Our rental sleds are mainly from Northern Sledworks. We use these because they are still pretty light but a lot more robust. Siglin sleds of course also can be purchased. I have some here Germany and if you are from outside the EU you can of course get them right from the manufacturer.
If you take a duffle bag or some other kind of bag to store your equipment on the sled, keep in mind that the snow in your sled may melt and get things wet from underneath. Also, if the bag has a zip it should be a good one as small or bad zips in the cold may not work for long. And of course it were great if the bag is as light as possible.
Organise your sled really well. It can be very frustrating if you always have to look for 10 minutes before you find what you are looking for. Use smaller bags in the big bag. Color code these.
Don’t load your sled to high and keep the heavy stuff at the bottom. If you don’t have the snowsled straps, get some other straps to keep your gear in place.
Participants of the MYAU can rent sleds and accessories. That saves money and also the trouble of getting the sled to the Yukon and back home again. Check with your airline before booking how much they charge for bulky or sports luggage.

Advice on sleeping system

A mat and a bivvy bag or tent also are part of a sleeping system. Apart from that you should also use a liner or a vapour barrier liner (VBL).
The mat plays a very important role as your body weight will compress the fill of your sleeping bag. So the only thing between you and the cold ground is the mat. There are many different options on the market. If you get a modern self inflating mats or hi-tech air mats you should combine it with a foam mat. That way if your main mat does not work you have an emergency back-up.
As for the sleeping, synthetic bags are getting better. But I still think for packing size and warmth to weight ration down is unbeatable.
If you borrow a bag from a friend make sure it still has got its full loft. If the bag was stored in the stuff sack for a long time you will likely not be able to use it.
We do use the extreme temperature rating to determine what sleeping bag you can use (see rules). However, keep in mind that at this temperature you may already have a horrible night. That is why not only your sleeping bag needs to work. And of course you can use your down jacket and other clothing to get some more insulation.
It also matters where you sleep and how you set up the place. How and where you build your fire, etc. Avoid cold spots (like lakes or rivers to rest), stay out of the wind. A fire is a good idea but be careful that you sleeping bag does not get too close to the heat. Flying sparks can also be a problem.
Some people like to have a tent. And it can work fine. However, at – 40 putting up and taking down a tent can be pretty difficult. Not every tent pole can handle these kind of temperatures. So, if you get a tent make sure it’s easy to handle and made for such cold temperatures. Should you decide to use your stove inside the tent beware that most manufacturers will tell you not to do so. It can be very dangerous.

Advice on shoes and snowshoes

Athletes have of course already used many different shoes for the MYAU. I would say most shoes have been trail running shoes with a waterproof membrane. Choice of shoe is a very individual thing. If you easily get blisters you may want to try it without a Gore-Tex shoe but take waterproof socks. Also, there has been feedback that if temperature changes dramatically every day (so, e.g. from – 10 degrees C during the day to – 40 at night) membranes can break. Think about how you may repair your shoes. Possibly take a back-up pair into you first drop bag.
One thing is for sure, warm winter hiking boots, like some companies offer them, normally are not the best choice. When walking in them your feet will get so hot that within hours you will have the first blisters.
Whatever shoes you get, make sure you give yourself plenty of time to train in them.
When buying your shoes for the MYAU keep in mind that you may have several layers of socks and/or very thick socks. And as in any ultra your feet will likely swell up.
A useful product, certainly for the 300 and 430 miles are the Neos Overshoes. You can wear these over your running shoes. They are wind- and waterproof and do not breath. So, they also act as a vapour barrier liner keeping back body heat when it gets really cold. And the waterproofness is great when you get to a place with overflow. These Overshoes are not easy to get in Europe. But you can order from North America or ask Coast Mountain Sports in Whitehorse to reserve a pair in your size.
Snow conditions can vary significantly at the MYAU. Having a lightweight snowshoe that has a deep cleat will give you the best traction on windblown sections of trail with deeper snow when snowshoes are required. Dion Snowshoes offer great energy return properties and optimal traction to allow for an efficient stride while running or hiking.

Advice on headlamps

Under normal circumstance you will be spending a lot of time on the trail at night. Especially when you do the 300 and 430 miles. So, really you do not want to compromise too much on your headlamp.
Have a close look at the range of the light and the battery life. You do not need the most powerful headlamps on the market but a certain light range is good as it will help you pick up the reflective tape on the Quest markers. The longer the battery life the less batteries you will have to take along. Thus saving weight.
I would say a very compact back-up headlamp is a must. You never know and the smaller headlamps usually are not that expensive.
Keep in mind that we want you to use your headlamp even if the moon would actually allow you to move without it. Dog teams and our guides and other people on ski-doo need to see you. Otherwise there may be accidents.
A separate battery pack definitely makes sense. You can have the batteries close to body heat. Which will give you a much longer battery life.
Lithium batteries will last a lot longer and most headlamps are compatible with them. But do check compatibility.

Advice on hydration

If you carry a hydration bladder have it as close to your body heat as possible, e.g. over your 1st layer but under your 2nd layer. Even if it is insulated.
Very often the mouthpiece or tube freeze. So, both should be insulated. Have the tube under your arm. Keep the mouthpiece inside if possible. Blowing the water out of the mouthpiece and tube can help keeping it from freezing.
Nothing beats a thermos when it comes to keeping your water hot/warm.
You can put chemical heatpads on to plastic bottles. Coke can stay liquid for quite a while that way. But it won’t last forever.
Do not underestimate your need for hydration in the cold. If you do not drink enough the risk of frostbike and hypothermia increases a lot. Not to mention all other problems that go along with lack of hydration.
If it is part of your strategy to stop and melt snow, keep in mind that this can be pretty time consuming. Melting ice is more efficient but you may not always have ice near you …

Advice on food

Try your food at home / in training first. You may love the real food and be really disappointed from the expedition meal version.
If you know that you need plenty of food during a race, take enough extra food for between checkpoints. We do serve good size portions but these can’t replace the calories you will burn. And distances between checkpoints are loooong.
Some athletes make the mistake of eating too many energy bars and drinking too many gels. This may cause stomach issues. So plan for a good variation of snacks.
If your food has got a certain size, i.e. you need to take a bite, make sure you pre-cut it or have it close to body heat before you eat it. Otherwise it may be frozen rock solid and challenging to get it into you.
Don’t just take sweet stuff. Salty food can be a nice change every now and then.

Advice on other gear:

As you noticed the focus on the above list is on the athletes on foot. It does not contain info on bike or xc-ski specific gear like bike, bike accessories, xc-ski, etc. But hopefully also our bikers and xc-skiers will find some useful info
Many athletes like listening to music while on the trail. Please keep in mind that you may not hear ski-doos or dog teams approaching. So, if the trail is very winding maybe rather not listen to music or at least keep your eyes open.
Don’t get your pack sacks too big. Otherwise, you will not improve your organisation. As always what you want will be at the bottom …
Not listed above but by now mandatory: a decent saw for cutting wood, when there only trees around but no branches to burn.

Almost all of the above is available in our racelite.de online-shop. If you have any gear related questions, please do not hesitate to ask. Athletes who sign up for the race get a 20% discount for shopping on montane.com.
