The Ultra Trail of the Mont Blanc starts in Chamonix, on the French side of Mont-Blanc. This part of the circuit is the friendliest: beautiful valleys, forest paths, mellow curves and an incomparable flora.

Then, a balcony-style path unveils the Italian side. This part of the trail is bordered by a fierce and dark rock face, bristling with peaks. After the Italian Val Ferret, the Swiss Val Ferret offers a return to a friendlier view of the mountains.

The Mont-Blanc area, a unique and genuine region, invites you, in the course of this hike, to discovery its varied and majestic scenery. You will be astonished with the impressive massif of the Mont-Blanc, omnipresent in front of your gaze throughout the circuit.

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 through seven valleys, over 71 glaciers and 400 summits, in an alpine décor which is unique in the world.

Many concerts and festivals will take place in the town of Chamonix!

New race 2018: MCC

New race MCC "From Martigny-Combe to Chamonix": 40km of festivities created for volunteers and local inhabitants of the Espace Mont-Blanc.

The runners will leave from Martigny-Combe (Switzerland) along an itinerary that will finish in Chamonix. The event will pass along little known paths and give the participants a route through the most beautiful hamlets in Chamonix's upper valley.

The UTMB organisation is ensuring that this new event will be conceived with the same high standard qualities as their other races. By starting on Monday morning, it will only be run during daytime which will mean that each volunteer can join their team for the rest of the week.

Route Map - MCC 2018

A unique French-Swiss route

This French-Swiss route of 40 km with no less than 2300m ascent, climbs up through the vines of Martigny-Combe to the col de la Forclaz then the col de Balme will appeal to the participants' uphill capacities and already it has the air of being an eminently festive race with its descent from the col de Balme to Chamonix.

The MCC is principally reserved for UTMB volunteers and local runners. It will be open to other runners, within the limit of places available, after the registration of volunteers and local runners.

Particular registration conditions apply to each of these groups.

Registration will open from 23th March 2018 to 2nd April 2018!
