Le Trail des Vallons de Cérences is a late-afternoon trail running event held at Stade Auguste Legendre in Cérences, Manche. Races start and finish on the stadium grounds. The program centers on short, timed trail races. Editions have included pairs like 8 km and 12 km, or 7 km and 15 km, alongside a walk and children's races. The timed races are registered with the French athletics federation and employ Smile Event27 timing, positioning it as an organized local race day rather than a casual group run.
The format is designed to be family-friendly. The walk is open to everyone, children's races are included, and bib pickup occurs on site before the afternoon begins. The event is organized by the APEL of Notre-Dame school in Cérences, in conjunction with AS Cérences. The stadium location provides convenient access to food and drink near the finish line. Entry fees are reasonable, the participant limit is 999, and online registration is managed via Normandie Course à Pied.
