Discover the route

Take part in the Tour du Mont Blanc Cyclo en DUO and cover 330km and 8300m of ascent in a relay format.

After a 5 a.m. start, it’s straight downhill to Megève. A gradual succession of Vaudagne and Col des Montets passes will take you towards Switzerland and the canton of Valais. There, the Col de la Forclaz awaits you. Once past the summit, you’ll find the day’s second feed station at the foot of the first major climb of the day, the Champex ascent.

Save your strength before handing over to your partner, as the final climb of the day is more than likely the most difficult. C’est bien le mythique Col du Grand Saint-Bernard qui vous attends ! At the summit, you’ll have a chance to refuel, but more importantly, you’ll be able to pass the baton to your partner. It’s now up to them to tackle the second part of the route. 

This second part begins directly with the crossing of the Italian border and a long descent into the Aosta Valley

For this second relay, no less than 175km await you, with around 4,000m of ascent. Almost all of this is to be found on three legendary mountain passes: the Petit Saint-Bernard, the Cormet de Roselend and the Col des Saisies, the last hurdle before the finish in this beautiful resort!

VIGILANCE : l’organisation n’est pas responsable du transport vers et depuis la zone de relai au sommet du Grand Saint-Bernard. C’est aux binômes de prévoir leur propre transport.
