The Montfort Trail is a small trail-running event held in Saint-Laurent-sur-Sèvre, located in the Pays de la Loire region of western France. Taking place in autumn, it features races ranging from 5 km to 21 km, alongside a 5 km walk and children's races. The event was established by the Montfort school parents' association, with technical support from the local Entente Sèvre club. Proceeds from the event contribute to funding activities for the school's pupils.
The routes follow the paths around Saint-Laurent-sur-Sèvre and the Sèvre valley, giving the day a character more akin to a local trail outing than a large city road race. Both licensed and non-licensed runners are welcome, and the events are open to both women and men. The programme caters to various skill levels: a 5 km race for beginners, 12 km and 21 km options for increased distance, a walk for those not running, and children's races that maintain the school-community focus of the event.
