The Fort Challenge, a unique race combining nature, stunning scenery and the 917 steps of Fort l'Écluse to climb. Get ready!
The Fort L'Ecluse Challenge is a unique race on an exceptional site; a site steeped in history, combining both cultural heritage and grandiose landscapes…

Its courses of 12 or 19km, mix roads and paths, wide tracks and monotraces...

Departing from the village of Léaz, the routes cross spectacular landscapes, particularly near the listed site of the Virgin of Léaz overlooking the Rhône, and the gorge of the Ecluse. But the strong point of this trail is the passage in the incredible underground gallery of Fort l'Ecluse and its 917 steps.

Participants must be at least 20 years old on the day of the race for the 19km and 18 years old on the day of the race for the 12km and be in good physical condition. Registrations will only be validated if they are accompanied by a photocopy of the FFA license; for non-licensees and licensees of another federation, a medical certificate of non-contraindication to the practice of running in competition dating from less than one year to 15/10/2023 is required. Because of his commitment, each runner authorizes the organizer to use the images on which he could appear, taken during the event. The number of participants is limited to 400 runners for the 19km and 250 runners for the 12.
