Environment

Because we are the privileged witnesses of climate change, the Mont-Blanc Marathon is committed to offering the valley's inhabitants and visitors an innovative model for sporting and cultural events designed to reduce environmental impact in a sustainable way.

Since the creation of the Cross du Mont-Blanc in 1979, the Club des Sports de Chamonix has been actively committed to offering quality races while limiting their impact on the environment. With this in mind, each year we assess the event's carbon footprint and implement a number of strong actions, which we reinforce from one year to the next.
