Tout Cattenom Court starts and finishes on the Esplanade de Cattenom in Cattenom, a village in France’s Moselle area near the Luxembourg border. It is a spring running event organized by Run'In Energy, with trail-style courses through the local woods and a walking option for people who want the route without racing it. The main distances are 10 km and 18 km, though some listings also describe the longer option as 20 km.
The course’s standout detail is the passage through Fort du Galgenberg, so this is not just a forest run with standard paths. The 10 km route suits runners and walkers who want a shorter outing on trails, while the longer route is aimed at people looking for a tougher nature run. Aid is simple: water on the 10 km course, water plus a small snack on the longer course, and a larger refreshment stop at the finish. Finishers receive a reward, and there is small food service on site after the race.
