Mythical race in a unique place!
The Mont Blanc Marathon is a trail event with 8 races. Several courses are proposed to runners from all over the world to participate with family or friends.
More than 10,500 runners of 80 different nationalities will have the joy of setting off from Chamonix to cover the trails of the Valley.
The Mont-Blanc Marathon races are organised by the Association of Sports Clubs of Chamonix. Under the name Marathon du Mont-Blanc, 8 races are organised: 90 km du Mont-Blanc, 42 km du Mont-Blanc, 23 km du Mont-Blanc, KM Vertical du Mont-Blanc, Starry Duet, Young Race Marathon, 10 km du Mont-Blanc Blanc and Mini Cross du Mont-Blanc (800m to 3 km reserved for children according to their age category).
During 4 days, the Chamonix valley will vibrate to the rhythm of the races, 40 000 people will be present in Chamonix to attend or participate in this event, and everything is done to welcome the runners and the spectators in the best conditions. The event has become considerable in just a few years, however, the organisation is associative (non-profit making) and relies on volunteers and the will of the local authorities.
With races taking place in the mountains in a sometimes difficult environment (notably the 90 km of Mont-Blanc), the runners must be aware of this particularity and prepare themselves properly. Each runner can find a race adapted to his level of practice that allows him to discover this unique environment that is the Chamonix-Mont-Blanc valley.
