The Muco Trail du Pays de Nemours begins at the Maison des Verriers in Bagneaux-sur-Loing, a commune in Seine-et-Marne, southeast of Paris. Organized by Pays de Nemours Running Trail, this trail-running event has a 600-runner limit across all its races to prevent trail congestion. Participants can select between two distances: the 11 km Coquelicots course or the 22 km Verriers course.
The courses are technical, winding through Bagneaux-sur-Loing, Faÿ-lès-Nemours, and Bougligny, rather than being flat road runs. This is the event's ninth year, and it supports a charitable cause: two euros from each registration fee are donated to Vaincre la Mucoviscidose, an organization assisting individuals with cystic fibrosis and their families. It is well-suited for club runners, corporate teams, and friends seeking a local trail race that contributes to a meaningful cause.
