Far North adventurer Thierry Corbarieu, on the IDITAROD 1000 in Alaska!
Ultra-trail runner and adventurer Thierry Corbarieu has taken on the IDITAROD Trail 1,000! This long-distance race in polar conditions, considered the longest and most difficult in the world, takes place in Alaska. Participants have 30 days to travel from Anchorage to Nome on foot, by bike or on skis, covering 1,000 miles — 1,600 km — with no assistance whatsoever…

In 2022, Thierry Corbarieu finished 1st on the Iditarod 350 (miles) — 500 km on foot — which earned him his entry ticket to this format three times longer: the IDITAROD 1,000. Today, he is covering the 1,600 km on foot that separates the city of Anchorage from Nome in Alaska. An extraordinary adventure that leaves no room for error or imprecision. That is why this race is open only to a handful of men with exceptional metabolism and mental strength. Indeed, each year only around thirty individuals take part.
Iditarod 1000, extreme conditions
Regarded as the longest and most difficult polar ultra-marathon in the world, the ITI 1000's 2023 edition features 27 participants on skis, by bike or on foot. Facing extreme and ever-changing conditions — wind, rain, mud, snowstorms and blinding sun — each competitor can rely only on themselves. Thierry Corbarieu, adventurer and Cimalp ambassador, takes on this unrelenting challenge head-on.
