Trail des Nouettes guides participants through the wooded areas of Versailles, near the renowned château and its grounds. The event offers five distinct options: two trail races, two Nordic walks, and a timed youth race, catering to adults seeking a challenging hilly trail and younger participants in the Benjamin and Minime categories.
The primary Trail des Nouettes is an 18 km single-loop race featuring 350 m of elevation gain. The Course de la Dauphine spans 10 km with 160 m of climbing across two loops. For younger runners, the Petit Trail provides a timed 3 km course. Walkers have dedicated routes: the Marche Nordique Royale is 13 km with 200 m of climbing over two loops, and the Virée de la Fontaine is a 10 km leisurely Nordic walk with 160 m of elevation gain.
