The 10 Km de Guichen is a road race held in Guichen, Brittany, starting from the Stade Charles Gautier track area in October. Athétic Pont-Réan Guichen organizes the event, offering two measured courses: a 5 km race beginning in front of the track and a 10 km race commencing on the track itself.
The 10 km course follows the same rolling loop twice, whereas the 5 km runners complete one loop before finishing on the track. The 10 km race includes a water station at the 5 km mark. Registrations are managed online via Klikego, with no option for on-site sign-ups. The organizers intend for the event to achieve an official label.
