The Trail de la Butte de Thil is a small trail event based in Précy-sous-Thil, with the start and finish in the village. Runners choose between 9 km and 17 km routes, both starting in the morning, and there is also a 9 km hike for walkers. The race is organized by Trail du Vieux Semur and is in its second edition.
The route runs on hilly ground through the woods around the medieval fortress of Thil, which sits above the area and gives the event its main landmark. It is a local trail day rather than a huge race festival: one edition had 214 runners across the two distances. The short format, forest paths, climbs, and castle setting make it easy to understand what the race is about.
