This is first and foremost for overall safety of riders, but also in order to provide the best possible support to all riders on the road. Despite these limited numbers, each event is accompanied by a four-vehicle support team.

The Cent Cols Challenges involve climbing 100 Cols in ten days, cycling approximately 200 kms per day with 4,500 – 5,000 metres of ascension on each stage. The first routes were inspired by the “Randonnées Permanentes” of the Club des Cent Cols, which is where the whole concept of this type of challenge came from. As well as including most of the Classic Climbs, the jewels of these routes are the many lesser known climbs. EACH EVENT INCLUDES A REST DAY BETWEEN STAGE FIVE AND SIX.

Preparation is the essential key to individual success, as well as to that of the whole event. Monthly motivation e-mails are designed to advise and inform you during the training period.

How much training time will you be able to put in once you have registered?

“Phil, thank you again for your patience with us in the back. We rode as hard as we could. Please know that our experience at the back was as rich and sweet as those up front. It was a tremendous experience, that would not have been possible without your vision (route planning) and more importantly your organization.”
