Roc Trail
What is Roc Trail?
Yes, you read that right! From 2026 onwards, we’re adding a trail route to the Roc d’Ardenne programme. Fancy going all out on your mountain bike on Saturday and then loosening up your legs with a trail run on Sunday? Prefer to skip the MTB and enjoy a fantastic trail run with your running buddies on Sunday? You can! We offer two routes (10 km and 25 km) so every trail runner can find their perfect challenge. Just like with the MTB distances, we’ll provide plenty of refreshment points along the way to keep you “full of energy” right to the finish.

Supplies
5 feed zones will be provided for the BIG Roc Marathon. The organization will provide sufficient drinks and food for all riders.
These feed zones are accessible with a car without crossing the courses so that spectators or teams can get there.
Timing with chip
Time is measured using an electronic chip. This chip, located on the back of the bib number, measures the net time between the start and finish. This means that your time only starts running when you cross the start line. This extra service ensures a more accurate time measurement.
This chip is included in the entry fee and does not need to be returned after the race. Do not fold the bib number and do not remove the stickers on the chip.
