La Saintlo is a January nature trail race held in Saint-Laurent-d'Agny, a village in the Rhône department located approximately 30 minutes from Lyon. It features timed off-road courses, with primary distances of 9 km and 15 km, alongside shorter races for children and juniors.
The courses traverse the village and its surrounding countryside, making the event suitable for runners seeking a local trail experience without the commitment of a long mountain race. Organized by the Association des familles de Saint-Laurent d'Agny and the Tennis Club des Coteaux, its family-oriented course structure welcomes club runners, novice trail runners, children, and local volunteers during the same winter weekend.
