Trail des Garennes 2027

Trail des Garennes is a late-March trail and walking event held in Saint-Martin-la-Garenne, located in the Yvelines department of Île-de-France, France. This event focuses on nature, offering three course options: an 8 km trail run, a 14 km trail run, and an 8 km walk. Each course is a single loop, allowing participants to explore the local trails without repeating sections. The 14 km trail, featuring approximately 250 meters of elevation gain, is the most popular option. The 8 km courses provide a shorter route through the same forest environment for both runners and walkers. This event is suitable for club runners, experienced trail racers, and individuals seeking a clearly marked route through natural surroundings.
