Trail de Bois le Duc

Trail de Bois le Duc is a mid-October trail race in Vandoeuvre-les-Nancy, near Nancy in eastern France. It offers short and middle-distance off-road options, with adult races at 8 km, 14 km, 21 km, and sometimes 28 km, plus junior races of 3 km, 900 m, and 450 m. The climbs are present but not excessive: the adult routes range from about 170-200 m of gain on the 8 km to several hundred metres on the longer races, with one source listing the 21 km at 600 m D+. It is a local, practical trail day, not a large city event, and entries are capped to prevent trail congestion. The race area is situated near the Hopital de Brabois and public transport, simplifying access compared to many forest trail events. The schedule begins with the longer races in the morning, proceeding through shorter adult and youth events, with the smallest children's runs around midday. The organiser includes local touches: volunteers prepare surprises, runners receive a registration gift, and post-race food may feature a country buffet, Moroccan soup, and a popcorn machine. Strava segments are integrated into the event, allowing regular trail runners to target specific efforts alongside the finish line.
