The Trail des Dahus Sallanchards is a spring trail-running event held in Sallanches, Haute-Savoie, near the Ilettes lakes. It is scheduled to coincide with the transition from the ski season to warmer weather, offering a program that includes races for children and challenging mountain runs in the Préalpes.
The main event is L’ultime Dahu Sallanchard, a 24-hour backyard race. Participants complete a 6.5 km loop with approximately 330 m of elevation gain each hour. The weekend also features Les Dahus Courtisans, a 26 km semi-night race for pairs with 1,500 m of ascent, and Les Dahus Affolés, a shorter 15 km course featuring around 900 m of climbing.
