The Mont-Blanc Marathon

The Marathon du Mont-Blanc has an excellent worldwide reputation, based on its rich history.

The Marathon du Mont-Blanc is an annual event and it includes 8 races, which are run by more than 10,000 people from 80 different nationalities.

The marathon was initiated in 2003, which means that in 2019 the marathon will be run for the 17th time.

However, the race has a more substantial history than this, as the 23km du Mont-Blanc, which utilizes part of the same route as the marathon, has been run yearly since 1979.

In 2003, on the 25th edition of the 23 km du Mont-Blanc, which was known as the "Cross du Mont-Blanc", the Marathon du Mont-Blanc was added to the schedule. The other 6 races followed.

Volunteers are essential

The 41st edition of the Marathon du Mont-Blanc is organized by Chamonix Sports Club, an associative (non-profit) organization which relies on the help of volunteers.

From the 27th to the 30th of June 2019, Chamonix will vibrate under the rhythm of the races, with 40,000 people present to either join the races or root for the participants. 

Therefore, over 500 volunteers are needed to assure the smooth development of the event and the safety of the competitors, especially since the races often include difficult terrain as the trails go through the mountains.

Learn more about becoming a volunteer for the 41st edition of the Marathon du Mont-Blanc or contact Chamonix Sports Club at club@chamonixsport.com or via telephone at 04 50 53 11 57.
