Trail Sud Touraine is an early-season trail running event held in Barrou, France, offering races from 12 km to 46 km. The event provides a wide selection for a small trail race: a 46 km solo, a 46 km duo, a 23 km race, a 12 km race, a timed Nordic walk, and a hike for those who wish to follow the route without competing.
The race begins in Barrou and concludes in Chambon, crossing terrain that is almost entirely paths: 95% paths, 5% road, with no tracks mentioned. Runners will go through the Creuse and Claise area. The 46 km solo is part of the Challenge National Trail program; the 23 km race also awards ITRA Mountain Level 2 points, National League status, and 350 finisher points.
