Cancelled in 2020.

Committing oneself to running around Mont-Blanc is above all to experience an internal adventure, a unique experience where each participant will have to draw from their strengths and push their mental and physical limits in order to cross the finishing line. This extraordinary trip at the heart of the massif will permit trail-runners to cross valleys and passes in contact with the most beautiful summits, in an alpine décor which is unique in the world.

To participate or assist with the UTMB®, is to vibrate to the rhythm of the trail-running planet and to share an extraordinary festival at the heart of a territory which has been mobilised for the occasion. 2 000 volunteers from 15 different countries, 19 French, Italian and Swiss communes within the Mont-Blanc country all working for the success of the event and supporting the UTMB® runners. 16,000 supporters who are coming to encourage their nearest and dearest and more than 50,000 spectators who will visit the salon and participate in the animations in all the villages of the Mont-Blanc country.
