The Pays du Mont-Blanc mountain bike challenge

What is the MB Race?

MB Race was created in 2010 on the trails of Megève and Combloux! This mountain biking event, famous for its demanding and breathtaking courses, takes place in the Mont-Blanc region.

MB Race is unique in the mountain bike scene since it is the only one to include a one-day race with a distance of 140 km and 7,000 m of D+! The MB Ultra Somfy, the event’s flagship race, counted just one finisher in 2010. Today, it is known as the toughest MTB race in the world!

Since 2010, the MB Race has established itself as a major event, both in the region and in the mountain bike world, becoming a major mountain bike festival with no fewer than 8 events on the program. The event is open to all, whether you are a cycling enthusiast, young or old, with friends or family… there is a race for everyone!
