Trail Blanc de Lans-en-Vercors 2027

The Trail Blanc de Lans-en-Vercors is a night trail race on snow, beginning in the village of Lans-en-Vercors, Isère, within France’s Auvergne-Rhône-Alpes region. It takes place in early March, a time when the Vercors area typically retains winter snow but the season starts to transition. Participants can select between short and longer race distances, including an 8 km option and a more extended route, alongside a relay format for teams. This event is part of the Trail Blanc series, focusing on running mountain trails in winter conditions after sunset, requiring a functional headlamp.
