Trail'ethon des Enclaves is a night trail race run for the Telethon des Enclaves. Runners start with headlamps in the dark, focusing on moving through woodland and wet ground rather than a road-race pace. Trail shoes are strongly encouraged, suitable for experienced trail runners and those seeking a more playful outing.
The route follows rivers, passes through the woods of the Enclaves, crosses a footbridge, and reaches the area near the lake. Muddy sections are expected, so clean shoes will not remain so. Maxime Cazajous, a champion trail runner, is the event patron, linking the local fundraiser to serious mountain and trail running.
