Mont-Blanc Marathon
The Mont Blanc Marathon is a trail running event organized by the Chamonix Sports Club, a nonprofit organization founded in 1905.

Our organization, committed to environmental stewardship, is dedicated to offering you an innovative and sustainable sporting event based on respect for the Chamonix Valley and its residents.
