Crohn en course is a running event in Lyon, scheduled for July with the exact day still to be confirmed. The program offers runners four choices: a 1 km children's race, plus 5 km, 10 km, and 20 km races for older participants.
The listing provides no course details beyond the distances, so the main characteristic of the event is its range: families can start with the children's race, while adults can choose anything from a short 5 km run to a 20 km effort. It is listed on the Miles Republic race platform under road running categories for less than 5 km, 5 km, 10 km, and 20 km.
