Route 4 châteaux - Saint-Rémy-lès-Chevreuse 2026

The Route des 4 châteaux de Chevreuse is a trail race held in mid-November in Saint-Rémy-lès-Chevreuse, located in the Yvelines department of Île-de-France, near Chevreuse. Contrary to its name, the route actually passes five châteaux, a distinctive feature for this nature-focused race. The advertised distance is approximately 17 km, with the primary 18.5 km Trail option featuring around 275 meters of elevation gain. The course is designed for trail runners, incorporating château vistas, woodland paths, and undulating terrain in the Chevreuse region. It is part of the Île-de-France running schedule and is managed by Miles Republic. A race description refers to participants as “preux finishers,” or valiant finishers, aligning with the medieval château theme without adding undue formality.
