The Trail de la Saint Aubeu is a trail running event held in Cormicy, a commune in the Marne department of northeastern France. It features two running distances: a 25 km trail with 600 meters of elevation gain and a 13 km trail with 360 meters of elevation gain. A 10 km walk is also available, ensuring the event is accessible to non-runners.
The routes traverse the Saint-Thierry massif, providing a hilly, woodland environment for the races, distinct from a flat road race. The 25 km option presents a more challenging course, while the 13 km offers a shorter, yet still significantly hilly, trail experience. ABEP CORMICY organizes the event, with modest entry fees of 13 EUR for the 25 km and 9 EUR for the 13 km.
