Roc d'Ardenne
What is Roc d'Ardenne?
The Roc d’Ardenne (59.4km) is the flagship race of the event. The pinnacle of achievement for any mountain biker. The programme features a beautiful 66km course with some challenging elevation changes. It is shorter than the Roc Marathon in terms of distance, but in terms of effort and stamina, it should not be underestimated.
Participants with a UCI ID will automatically start in wave 1.
All other participants will be assigned to the remaining waves based on their registration time: those who register first will have priority in the first available wave, and so on.
