Trail de la vallée de la thure by night - Cousolre 2026

The Trail de la Vallée de la Thure by Night is a 12 km night trail race held in Cousolre, Nord department, Hauts-de-France. Typically run in early November, the main race begins at 18:30, requiring participants to use headlamps from the start. The 12 km course includes a 270-metre climb, offering a challenge suitable for both new trail runners and seasoned athletes. The route crosses forest paths, steep ascents, technical terrain, concealed roots, and areas near Cousolre's former quarries. It presents a demanding trail run, not a straightforward road race, featuring descents that challenge balance and speed. RRunning Cousolre organizes the event, fostering a local and welcoming atmosphere where night-trail regulars and newcomers share the course. Post-race, participants receive homemade soup and substantial refreshments, aligning with the event's straightforward concept: compete intensely in the dark, then recuperate together.
