Photo by Martin Hartley

i. What to expect: Frigid temperatures, lonely snow-covered landscapes and a true test of your stamina, no matter who you are! The race takes place over the trail of the toughest sled dog race in the world, only you won’t have any dogs to pull you along! Whichever race length you chose, you’ll encounter snow, ice, breaking trail, frozen river crossings and temperatures as low as -40! It isn’t called “the world’s coldest and toughest adventure race” for no reason!

ii. Race Difficulty: Undoubtedly the most extreme adventure on our list. Even the 26-mile and 100-mile events will expose you to the wildest terrain and conditions the Yukon has to offer and only the toughest competitors are likely to reach the finish. The longest race varies annually from 300 miles to 430 miles long…wow!

iii. Cost: $3000 (300-430-mile race)
