Trail of the Glières 2026

The Trail des Glières 2026 (15th edition) is a two-day mountain trail event centred on the Plateau des Glières and the Thorens‑Glières locality in Haute‑Savoie, France. The programme brings together multiple distance options for trail runners, ranging from a steep vertical kilometre (KV des Glières) to long ultra routes, with route profiles that include very large elevation gains and high alpine plateaux. The event emphasises panoramic mountain scenery, challenging ascents and descents, and a sporting festival atmosphere with partners and on‑site activities.

Information published on the official site confirms dates of 3 and 4 October 2026 and that registration for the 2026 edition will open in early June; detailed start times and individual race pages are provided by the organiser and linked race pages. The event web pages and affiliated result/media pages show extensive past‑edition results, photo galleries and partner listings, underlining a well‑established annual trail meeting on the Glières plateau. Participants should consult the official race pages for final start times, course maps and safety information closer to the event.
