Trail du fort de guentrange - Thionville 2026

The Trail du Fort de Guentrange is a trail-running event held at Salle du Val Marie in Thionville. The routes encircle the Fort de Guentrange, a military installation from the late 19th century situated above the town. Typically, the event offers a shorter, hilly course of approximately 10 km with about 300 m of elevation gain, and a longer course of 22 to 23 km featuring around 800 m of climbing. A 10 km walk is also sometimes available, making the day accessible to those not solely focused on experienced trail running. The course crosses forest paths, inclines, and the terrain surrounding the historic fort, emphasizing climbing and varied ground over flat-road speed. The Trail du Fort de Guentrange association, supported by volunteers, local community backing, and sponsors, organizes the race. The event also draws attention to Le Rire Médecin, an organization assisting hospitalized children, and Help4Mada, which aids vulnerable populations in Madagascar. Participants can generally register online or at the venue shortly before the event. Registered runners typically receive a beverage and a pizza slice. The day's activities may also include music, food vendors, and guided tours of the fort.
