The ultimate trail running event, uniting trail runners from around the world, the UTMB Mont-Blanc, Finals of the UTMB World Series, brings together in Chamonix the world's top elites, as well as more than 10,000 passionate runners to participate in one of the eight races of the UTMB Mont-Blanc.
The Trail Running Adventure of a Lifetime
Running around Mont Blanc is above all an inner adventure, a unique experience where each participant will have to draw on their strength and push their mental and physical limits to cross the finish line. This extraordinary journey in the heart of the massif will allow the trailers to cross valleys and passes in contact with the most beautiful summits, in a unique alpine setting.
Vibrate to the rhythm of the races
To participate or attend the UTMB Mont-Blanc is to vibrate to the rhythm of the trail planet and to share an extraordinary celebration in the heart of a territory mobilized for the occasion.
Each year, 2,000 volunteers from 15 different countries, as well as the 18 French, Italian and Swiss municipalities of the Mont Blanc region work to ensure the success of the event and support the runners of the UTMB Mont Blanc. 20,000 supporters come to encourage their loved ones and more than 50,000 spectators visit the show and participate in the activities in all the villages of the Mont Blanc region.

The origin of the UTMB World Series
Since its start in Chamonix in 2003, and building on that success ever since, the UTMB Mont-Blanc has grown to be the world's leading trail event and is the inspiration behind the creation of the UTMB World Series circuit, based on the same founding principles: surpassing one's limits, fair play, respect for people and the environment and solidarity.
Starting in 2023, UTMB Mont-Blanc will host the prestigious UTMB World Series Finals each year, crowning champions on its three iconic races: UTMB, CCC and OCC.
