The MB Ultra Somfy is the flagship race of the event! Much more than a race, it’s above all a challenge against oneself… The grail for every participant taking part in the race is to become Finisher of the 140 km, the queen distance! And of the 1,500 participants taking part, only a few will succeed…
The course is divided into three distances: 70 km & 3,000 m elevation gain | 100 km & 5,000 m elevation gain | 140 km & 7,000 m elevation gain. After a joint start, riders can decide in due course whether to stop or continue to the final distance, joining the coveted Finisher’s Circle of the world’s toughest mountain bike race.
The event has also been awarded the UCI XCM Hors Classe label for the 70km distance for both men and women.
And if that’s not enough, another challenge awaits you! Combine the MB Ultra and the MB Explore to win exclusive gifts!
