Messimy Trail is a small trail race in Messimy, France, located in the Monts du Lyonnais, west of Lyon. It offers two hilly off-road options: a short course of approximately 10.9 km with 425-430 m of elevation gain, and a longer course of about 19.4 km with 708-750 m of elevation gain. Both races begin and end at the Salle du Vourlat in Messimy. The event is limited to 499 participants across both distances.
The course follows local paths and climbs in the Monts du Lyonnais, ensuring even the shorter race provides a genuine trail experience, distinct from a flat village run. Aid stations are provided, and participants receive a post-race meal. The event maintains a community atmosphere with modest entry fees, timing by SG CHRONO, and all profits benefiting the Telethon, the French fundraising campaign for medical research and family support.
