Trail du Blanc Pignon guides participants through woods, along riverbanks, and across old private estates near La Calotterie in Pas-de-Calais. This February event offers three trail distances: 10 km with approximately 150 m elevation gain, 15 km with about 300 m, and 30 km with around 500 m. A 10 km Nordic walk is also available, catering to those not solely focused on the longest run.
The routes combine roads, dirt paths, and technical singletrack, featuring winding woodland sections and stretches alongside the Canche river. They traverse the natural surroundings of Montreuil-sur-Mer and its ramparts, as well as private properties like a castle estate and woods opened specifically for the occasion. The February conditions can challenge footing and ascents, and staggered starts help manage the finish area for the several hundred participants.
