Trail of the Petit Saint-Bernard

The Trail du Petit Saint-Bernard (TPSB) is a high‑altitude mountain trail weekend held around Les Chapieux and Bourg‑Saint‑Maurice in Savoie, France. The event brings multiple distinct races together under one edition, from a short Verticale and a 10 km up to long trail distances and an ultra option that combines two races over two days. Routes traverse alpine passes and high cols with extensive technical and exposed sections, offering panoramic views of the Mont Blanc massif and the Vanoise area. The original French name, Trail du Petit Saint‑Bernard, is used across official communications and entry pages.

Logistics are concentrated at Lieu‑dit Les Chapieux / Bourg‑Saint‑Maurice with online registration via the official site (registration open for the 2026 edition and online enrolment stated as available until 22 September 2026). Some short events permit on‑site entry (notably the 10 km and the Verticale du Bonhomme) but most races require pre‑registration and a medical certificate or national athletics/triathlon licence to validate an entry. The weekend includes a TPSB Ultra option (a two‑day combination of the 35 km and 68 km races) with cumulative timing and prizes for overall and category placings, and races list aid stations and medical cover as part of the organiser’s provisions.
