The Pays du Mont-Blanc MTB 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!

But MB Race is also a great celebration of mountain biking, with no less than 9 different courses on the program… For all ages and all levels!
