Trail du Millésime is an October nature race held at Magrigne in Saint-Laurent-d’Arce, Gironde, southwest France. It provides three trail distances: 6.5 km, 12 km, and 22 km. The event is organized by Trail Event / Trail Events Association, a local group founded by Jean-Marc Fabre with assistance from Hervé Bertrand and Christophe Ruis. Approximately forty volunteers support the race day.
The routes traverse vineyards and the Natura 2000 site of Moron. Course adjustments are made to ensure each edition offers a distinct experience. Magrigne also features the chapel dedicated to Sainte-Quitterie, establishing a distinct local landmark at the race base. The inaugural event attracted 260 runners, 65 walkers, and 70 children, indicating an early mix of trail runners, walkers, and families. One euro from each entry fee is donated to Jeune et Rose. The finish line includes a prize list, a raffle with items like a stay in a Perigord gite, and a beer for all finishers.
