Like last year’s MB Ultra Somfy, the MB Explore will take place over 3 distances: 20 km, 35 km and 55 km, with 850m, 1500m and 2200m of D+ respectively. Depending on the state of your legs… and your head, you’ll be able to decide whether to stop or continue on to a longer distance!
What’s new is the 20 km, where the course has been redesigned to enable as many people as possible to take part in the first part of the race. You’ll start by tackling 850 m of D+, but the technical level will be lower on the descent to Megève.
Once in Megève, you’ll have the choice of stopping or continuing for a further 15 or 35 km. While the 35 km will take you to the well-known Le Jaillet sector, the 55 km east promises a magnificent mountain-biking experience!
The race is still open to the cadet category for the 20 km, and this year they’re likely to break new speed records!
