Trail Des 3 Etoiles - Saint Clar is a trail event in Saint-Clar structured around a unique star-shaped format. Runners begin with a 6 km loop and, at its conclusion, can choose to finish or add another loop. This decision results in three possible race distances from a single entry: 6 km, 12 km, or 21 km, with corresponding elevation gains of 100, 200, or 300 meters. The event is held at the Cantoloup Lavallee establishment, and the 13 EUR entry fee is uniform across all distances.
The course utilizes three loops instead of a single fixed route, accommodating cautious beginners, hikers, and runners seeking to extend their effort. The 6 km village loop includes a passage through the EHPAD, offering a local, community-oriented feature uncommon in most trail races. Its inaugural edition established this adaptable format, where the choice to continue is integrated into the race itself rather than being predetermined before the start.
