A group of trail runners setting off.

Race organizers at the world's most iconic trail running event have announced an innovative new scheme to cut carbon emissions, by incentivizing runners to choose low carbon travel.

In 2026, runners in the UTMB Mont-Blanc will receive recommendations for the most carbon-efficient travel route to the Chamonix area based on their home location. Those who follow the suggestions will be rewarded with a 30% bonus in the highly competitive lottery draw for the 100-mile race as well as the shorter-distance CCC, OCC and ETC races.
