About this race
This UTMB® is one of the most intense moments of the year for ultra runners. You'll run magnificent courses around Mont-Blanc, crossing borders, alpine forests, and high-altitude lakes. It's hard, long, and demanding. Be ready to fight to overcome the challenges, especially since the paths won't be marked, and you'll need to navigate yourself. A festive mountain atmosphere awaits at the finish, rewarding your effort in the heart of the Alps.
