The Grand Trail of Serre-Ponçon

Le Grand Trail de Serre-Ponçon 2026 is presented as a three-day trail running festival set around the Serre-Ponçon lake, with a lakeside village atmosphere and the start/finish area at the plan d'eau d'Embrun. The event is scheduled from 18 to 20 September 2026 and brings together multiple race formats for a broad range of trail runners. The festival framing emphasises an all-ages experience and a mix of competitive races and community activities centred on the lakeshore.

The race programme for 2026 lists several distances including 100 km, 60 km, 30 km, 15 km and a children’s parcours, with substantial elevation gains on the longer routes and technical mountain trails. Alongside the races the event features a Trail & Outdoor expo, free initiation sessions, food and drink areas with food trucks, and live entertainment including concerts and DJ sets. Participants and spectators alike are invited to the village environment at the plan d'eau, which is positioned as the hub for start/finish operations and festival activities.
