A mythical race, a unique experience
From August 23th to August 29th 2021
Live an extraordinary adventure in the heart of the Pays du Mont-Blanc
The UTMB® is the most incredible trail-running event! An essential event for trail-runners from all over the world. Each year, the best athletes meet in Chamonix and almost 10000 runners participate in one of the event's 7 races.
Running around Mont-Blanc is above all an inner adventure, a unique experience where each participant has to rely on their strength and push their mental and physical limits to cross the finish line. This extraordinary journey in the heart of the range allows runners to cross valleys and ridges in a unique alpine environment.
To participate or attend the UTMB® is to connect to the trail running world and share an extraordinary celebration in the heart of an amazing territory. 2000 volunteers from 15 countries and 18 French, Italian and Swiss municipalities of the Mont-Blanc region are working to ensure the success of the event and support the UTMB® runners. 20 000 supporters are coming to cheer on their loved ones and more than 50,000 spectators visit the show and take part in the activities in all the villages of the Pays du Mont-Blanc.
See you in Chamonix the last week of August to share this great adventure!
