Trail La Domaniale takes place in Saint-Cloud, west of Paris, within the national forest of Saint-Cloud in early October. Runners can choose between 12 km and 21 km distances, or an 8 km Nordic walk in the same setting. The 21 km route includes 340 meters of elevation gain, the 12 km has 200 meters, and the 8 km walk has 130 meters, meaning even the shortest option involves climbing.
The event, organized by volunteers from UAS Saint-Cloud, limits participation to 450 bibs for the 21 km, 350 for the 12 km, and 200 for the walk. The course winds through forest, nature, and the edges of town, avoiding remote mountain terrain. La Domaniale also benefits Fondation Arthritis, donating 1 euro from each bib, a portion of profits, and offering an additional donation option during registration.
