The Course nature du Val de Marque is a late-November nature-running event held in Hem, Nord department, France, beginning at Rue du Docteur Coubronne. Participants can choose from three running distances: approximately 26 km, 13 km, and 8 km, alongside an 8 km walk. The courses traverse the natural landscapes and neighboring communes of the Val de Marque, offering an outdoor trail experience rather than a typical road race.
The long course measures 25.6 km with roughly 85 m of elevation gain, and the short course is about 8.3 km with approximately 50 m of gain. These distances provide varied terrain without becoming a mountainous challenge. Recent events have seen around 1,700 participants, indicating its status as a significant local event. It also functions as the concluding stage of the Challenge Nord Évasion series. Aid stations will be available, and bibs can be collected the day before or on race morning.
