The Trail des Nouettes, held in October in Versailles and organized by Union Athlétique de Versailles, features a 10 km race called the Course de la Dauphine. This forest run includes approximately 160 m of elevation gain, beginning and ending at the Centre Sportif Jean-Marc Fresnel on rue Rémont.
All courses follow forest trails. The event also offers an 18 km trail race, a 3 km youth race, and 10 km and 13 km Nordic walking routes. It is designed for club athletes, seasoned trail runners, younger participants, and walkers seeking a woodland excursion in Versailles, distinct from an urban road race.
