The Ronde du Kercorb in Chalabre offers two mountain-style trail runs. Participants can select a 10.5 km course with 400 meters of elevation gain or a 21 km course with 900 meters of elevation gain.
The 10.5 km race begins at 08:00, followed by the 21 km race at 08:30. This marks the 8th edition of the series. The significant elevation in both routes ensures they are more than just an alternative to road running.
