Trail du Miosson is a winter trail race held near Saint-Benoît and Flée in western France. Its routes trace the Miosson area and its muddy paths. The race takes place in January and provides three distances: 8.8 km, 15.6 km, and 24 km. Now in its late-teen editions, it is a recurring event with an established volunteer team and local partner support.
The courses are set between Saint-Benoît and Flée, utilizing tracks and crossings around the Miosson instead of a road-race format. The 8.8 km and 15.6 km routes feature the descent from the SNCF bridge, while the 24 km route includes a crossing over the Miosson bridge. Recent editions have encountered wet weather and muddy conditions, consistent with a January trail race. Organizers share practical information before the event, results post-race, and photo galleries of the start, course points, and finishes.
