在加拿大的育空山区北极超级马拉松比赛中，一名孤独的选手在结冰的育空河上奔跑。
Billed as the world"s coldest and toughest ultramarathon, this February event requires runners to follow portions of the trail used in Canada"s Yukon Quest, a grueling sled dog race. During the 430-mile (692-kilometer) event, which has a 13-day time limit, runners can face temperatures well below 0 degrees Fahrenheit/Celsius, plus wind chills that are even lower. Fresh snow or high winds can render the marked path invisible, while river crossings can be deadly if the ice is unstable.
