Presentation
Mountain collection is THE must-attend event for cyclists!
Refuelling is offered at the summit.
This non-timed challenge is open to all cyclists (amateurs and experienced riders) on road bikes, mountain bikes, e-bikes or tandems! Everyone is welcome!
It’s a chance to (re)discover the passes and climbs of ‘La Maurienne, the world’s largest cycling area ©’, through varied panoramas and routes, in a friendly and relaxed atmosphere.
Enjoy it in complete safety! The road is closed to motor vehicles for the duration of each stage.
And at the finish, you’ll find a small refreshment stand to recharge your batteries!
Do pop into the Tourist Office where a ‘Pass Col’lector’ passport is available (€5) to commemorate your achievements: a stamp in your passport to validate each climb!
PLEASE NOTE, for all motor vehicles:
This event involves the closure of the D926 and D927 roads between the Col de la Croix de Fer and the last hamlet of St Colomban des Villards, via the Col du Glandon.
