You are looking for some snacks for the long stretches between checkpoints? Then you should try the expedition bread from the Alpine Bakery in Whitehorse. It is one of their first breads and great for the MYAU or other outdoor adventures. It will last 4 to 5 weeks without refrigeration. It’s sweet but not cake-like. Dense and easy to pack. All ingredients are organic.
There is a 200 g version for CAD 4.75 and a 1 kg version for CAD 19.75. The Alpine Bakery is on 411 Alexander Street.
