The Ultra Trail du Mont-Blanc (UTMB) in Chamonix is THE big event that trail enthusiasts look forward to.
Once again this year, from August 25 to 31, 2025, we'll all be vibrating to the rhythm of the 8 UTMB races, where surpassing oneself, fair play, respect and solidarity are the order of the day!
Discover the participants and the list of races on theUTMB website.
UTMB, AN EMBLEMATIC RACE
Inaugurated in the summer of 2003, the competition is now the world's most emblematic and prestigious trail race.
With a distance of 176 km and a positive altitude difference of 10,000 meters around Mont-Blanc, this is a real experience where each participant will have to draw on their last reserves of strength and push back their limits to cross the finish line.
We're still looking forward to strong, memorable memories!
