More than 10,500 runners from 80 different nationalities will have the joy of taking away from Chamonix to travel the trails of the Valley.
The Mont Blanc Marathon races are organized by the Chamonix Sports Club Association. Under the name Marathon du Mont-Blanc 8 races are organized: 90km from Mont Blanc, 42km from Mont-Blanc, 23km from Mont-Blanc, KM Vertical from Mont-Blanc, Starry Duet, Young Race Marathon, 10km from Mont-Blanc White and Mini cross of Mont Blanc (800m to 3km reserved for children according to their age categories). During 4 days, the Chamo-nix Valley will vibrate to the rhythm of the races, 40 000 people will be present on Chamonix to attend or participate in this event, and everything is done to welcome the runners, the accom-pagnants and the spectators in the best conditions. The event has become considerable in a few years, so our organization is associative (non-profit) and relies on volunteers and the will of local communities. Faced with the craze, we must organize to improve the well-being and safety of all, with races taking place in the mountains in a sometimes difficult environment (especially the 90 km of Mont Blanc), runners must be aware of this particularity and prepare properly. Each rider will be able to find a race adapted to his level of practice which allows him to discover this unique environment that is the Valley of Chamonix-Mont-Blanc.
