Every race at the Foulées de l'Ill concludes in Ensisheim, with runners beginning from various villages situated along the Ill river. This road race in the Haut-Rhin region features a half marathon, a two-person half-marathon relay, a 10 km race, and a 5 km race. The courses are flat, designed for consistent pacing rather than elevation gain. The half marathon begins in Niederhergheim, the 10 km in Munwiller, and the 5 km in Réguisheim. The event takes place in mid-October, organized by Team Com in conjunction with the Communauté de Communes du Centre Haut Rhin.
The half marathon and relay route traces the Ill river through nine municipalities: Niederhergheim, Oberhergheim, Biltzheim, Niederentzen, Oberentzen, Munwiller, Meyenheim, Réguisheim, and Ensisheim. Relay exchanges occur in Munwiller, which is also the starting point for the 10 km race. The 5 km event is open to runners and walkers, and it benefits Arc en ciel de Bernard, a charity supporting cancer patients. All finishers are awarded a medal, and participants have the option to reserve a shuttle service during registration for transport from Ensisheim back to their respective starting villages.
