The Club des Cent Cols, founded in 1972 and affiliated to the French Federation of Cyclotouring has prepared this “Randonnée Permanente” based on a simple theme: “One Hundred Cols”. The completion of these one hundred cols will allow you either to join the Club, or to progress with your list in the Club’s “Tableau d’Honneur”.

This route will allow you to discover or rediscover the high Alps in all their glory, and to take part in a breathtaking cyclo-mountain randonnée.

One hundred and four cols (including 5 at more than 2000 m above sea level) in 1,580 km (for a total climb of not less than 28,000 m), with the intriguing possibility of integrating Mont Ventoux as a variant.


The eight checks will be carried out at route points chosen by the randonnéur himself, a check being carried out in each section (the section numbers are to be found on the route map).
