Grand Trail of Serre-Ponçon 2026

The official Grand Trail de Serre-Ponçon (Le Grand Trail de Serre-Ponçon) returns in 2026 as a three-day festival-style trail weekend based in Embrun on the shores of the Lac de Serre-Ponçon. The event combines multiple running formats with a lakeside village featuring a Trail & Outdoor expo, free sport initiations, food and drink areas, concerts and DJ sets, and other on-site entertainment. The organisers highlight a commitment to sustainable development and to rooting the event in the local territory; the event pages note that detailed race routes are published on the site and that registration status for the 2026 edition has been confirmed on the event pages.

Racing is offered across several distances with looped courses designed to bring runners back through the festival village; the programme includes main formats from short to ultra distance plus a Trail Kids offering. The routes are described as scenic and demanding, traversing ridges and offering panoramic lake views, and several races carry UTMB index recognition. The event is promoted as family-friendly and spectator-oriented, expecting roughly 1.2K participants overall and supported by local partners including the Ville d'Embrun and the Communauté de Communes de Serre-Ponçon.
