The 10km de Belley is a road race in the town center of Belley, organized by ASA Belley with town support. The adult race covers exactly 10 km over two laps within the town, with a revised course ensuring the official distance. It suits both experienced runners aiming for a fast time and amateur runners seeking a local race within Belley's center.
The course winds through the streets of central Belley and concludes on the athletics track at Paul Chastel stadium, offering a stadium finish instead of a roadside one. Aid stations are positioned at the halfway point and after the finish line. The event accommodates participants with disabilities. Children's races take place on the athletics track, with on-site registration available. A portion of the profits supports research.
