The UTMB is a trail-running event full of superlatives! An essential event for trail-runners from all over the world. Each year, the elite of the trail-running world find themselves in Chamonix alongside almost 8000 runners keen to participate in one of the event's 5 races.
Committing oneself, to running around Mont-Blanc, is above all to experience an internal adventure, an 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 dcor 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.
The organisation offers 4 individual races (UTMB, CCC, TDS, OCC) and an adventure in teams (PTL) meaning welcoming almost 8000 participants coming from 87 different countries.

Go exploring Beaufortain!
The 11th edition of the TDS ® promises to be historic: more beautiful, more technical, more alive, it is a new adventure that awaits the runners with an enlarged passage in the Beaufortain.
A crossing under the sign of sharing and discovery, to meet the inhabitants of the valley, their know-how, their trails, but also and their natural and gastronomic heritage. With this incursion in the heart of the Beaufortain, the race that starts on the Traces of the Dukes of Savoy (TDS ® ) has never worn its name and its attachment to the territory. As for the challenge, it has never been so exciting and beautiful, raised and technical, wild and unusual.
Drawn by the board UTMB ® course based on the expertise of the local stage, Thierry Bochet, brilliant finisher of the PTL ® , the new course, which enters the heart of the Savoy, will pass through the must-see places of the massif such as the Pas d'Outray, a veritable belvedere of the Beaufortain, with its breathtaking view of the Pierra Menta and the Grand Mont , mythical places of ski-mountaineering, but also Mount Vorès and its alpine and green atmosphere where graze the Tarines and Abondances. Without forgetting the panoramas on the mythical lakes of the valley at the passage of the Gittaz, transporting the runners in full heart of the solid mass.
With its landscapes that the whole world envy us and its many remarkable points of passage (the Passeur de Pralognan, the Col de la Sauce or the passage of the Cure), the TDS ® is more than ever a race of international class and, l adventure of a lifetime.
