The MB RACE has been in existence since 2010. This demanding and breathtaking mountain bike race takes place in the Les Portes du Mont-Blanc area (Combloux, Megève, La Giettaz, Cordon, Sallanches). It stands out in the panorama of mountain biking because it is the only one that has such a long-distance one-day event: 140 km with 7000 meters of positive altitude difference. A race that counted only 1 finisher out of 600 riders in 2010, which earned it the toughest racing label in the world.

The event remains OPEN TO ALL with its 8 events offered.

2023 news coming (spring 2023).
