Trail Blanc Valloire SLA is a short winter trail race near Saint-Jean-de-Maurienne, starting in Valloire and Verneys. Participants can select a 1 km format, an untimed 5 km, or a timed 10 km. Because the event takes place in the evening, all participants must carry a front light.
The 1 km and 5 km races are open to participants aged 5 and up. The timed 10 km requires participants to be 16 or older. The event benefits Sois Là Aussi, an association supporting individuals with neurological diseases, their caregivers, and related research. A medical certificate or federal license is required for the 10 km, but not for the shorter untimed races, making them accessible for children, families, walkers, and casual runners alongside those seeking a timed performance.
