Cent Cols Challenges

100 cols, 10 days – a unique journey that tests and builds the body and spirit in equal measure.

The Cent Cols Challenge is the brainchild of endurance rider Phil Deeker, and his determination, commitment to riding and will to explore has created one of the ultimate tests of what is possible on a road bike. All of these trips take place across Europe, criss-crossing entire mountain ranges to combine the classic routes and climbs from the Grand Tours with lesser-known back-country gems.

2017 is set to be a very special year for the Cent Cols Challenge. To mark the end of the first decade of the story, and to celebrate his 60th birthday, Phil is challenging himself to complete the “Ride of a Thousand Cols” – ten CCCs ridden back-to-back, with just three days between each to plan and prepare for the next. Three of the ten trips – Corsica, Cevennes and Southern Alps – will run at a slower pace to help welcome new riders to the ever growing Cent Cols family. Visit Phil’s dedicated Cent Cols Challenge website for more information. The 2018 Cent Cols Challenges will be announced soon.

I think what makes these rides so very special is the fact that Phil and Rapha Travel even dare to attempt them: on paper, they look ridiculous and in practice, they are just that - but also, somehow, possible. Most riders have reserves they never knew existed and Phil's planning and ability to improvise, results in the majority of riders completing stages and events beyond their wildest dreams.

Friendships form quickly and deeply because of the severity of the stages and as the days go on, it's those friends around you who help to make things possible. All the usual stresses and distractions of life slip away and it becomes simply about managing your effort, your nutrition, your body, your kit and above all, just riding your bike. It's quite simply, perfect.

Am I strong enough for the trip?

Cent Cols Challenges are the toughest challenge. Our guides will support every rider to go beyond their usual level of riding but you should be able to spend 8 hours in the saddle for multiple days.

How does payment work?

We ask all customers to pay a deposit when they book, which confirms their reservation. The balance is due 60 days before departure – we’ll get in touch to remind you when it’s time. If you book less than 60 days before departure, we’ll ask you to pay the full trip price upfront.
