The Trail du Muguet - 30 km is a forest trail race held in Meudon, located in the Hauts-de-Seine department southwest of Paris. This race takes place within the Meudon state forest and is part of the Grand Paris Seine Ouest Nature Sports Festival. The 30 km is the longest distance offered, with other routes available down to 1 km.
The course is a nature run on forest paths, distinct from a road race through town. Participants can run solo or as part of a relay team, attracting both individuals seeking the full 30 km challenge and teams dividing the distance. Its core concept is a local trail event centered on the Meudon woods, featuring multiple distances to accommodate beginners, younger participants, and seasoned trail runners.
