Trail du Marensin - Vielle-Saint-Girons 2027

Trail du Marensin is a night trail race held in Vielle-Saint-Girons, a village within the Landes region of southwest France. Participants begin at the Yvonne Mester stadium and can select either a 10 km or a 21 km course. This setup accommodates individuals seeking a brief night run as well as those aiming for a half-marathon distance trail event. The race is now in its 17th year, indicating a well-established local event rather than a fleeting novelty. Its primary distinguishing characteristic is straightforward: both distances are completed after sunset. This transforms the Marensin trails into a headlamp-required race, where managing pace, maintaining footing, and staying alert become more critical than during a standard daytime road race.
