As a 3 time winner of the epic UTMB, Xavier Thévenard is one of the planet’s great trail athletes but for both Xavier and his sponsor On there’s one race that’s far more important to win…

…the race to prevent the catastrophic effects of climate change on our natural world. So athlete and sponsor have joined forces in a project that hopes to inspire the trail running community worldwide to change some behaviours, make more responsible choices and embrace a more sustainable lifestyle.

Watch our powerful Manifesto film and join Xavier on the trails of his beloved and beautiful Jura region as he explains why it’s time for us all to choose the right path.
