The TPSB, taking place on 26 and 27 September 2026, is the last high-altitude trail race of the year. The programme features a wide range of races in the heart of wild mountain terrain, from the Vertical Kilometer to the Ultra. This trail is considered by purists as one of the most beautiful mountain trails in France: authentic, with a touch of technical challenge and rustic simplicity. All race starts and finishes take place at Les Chapieux hamlet, Bourg-Saint-Maurice (73700).
