Trail des écluses - Castets et Castillon 2027

Trail des écluses is a trail-running and walking event in Gironde, Nouvelle-Aquitaine, southwest France. It begins and ends in Castets and Castillon, taking place in April with a concise schedule: a 16 km timed trail race, an 8.5 km timed trail race, and an 8.5 km walk without timing. The route runs alongside the Canal Latéral à la Garonne, making the canal the primary element instead of a mountain or forest setting. The participation is modest, with approximately 200 runners anticipated for each timed race and about 150 walkers. The organization is straightforward: starts are spread throughout the morning, and parking and showers are provided on location.
