Saint-François-Longchamp, Maurienne Valley, Savoie, France
Triathlon de la Madeleine is a mountain triathlon held in the Maurienne valley and branded on the site as “Le Triathlon Montagnard”. The 2026 edition is scheduled for Saturday 22 August 2026 in Saint-François-Longchamp and the event offers three distance formats (S-1200, M-2200 and L-3400) plus a children’s Animathlon. The race is promoted for its alpine scenery and demanding climbs, with course briefings, 3D parcours material and linked programme pages available on the official site.
The event combines open-water swimming at the Saint-Rémy-de-Maurienne lake, long mountain cycling legs that climb classic cols, and running finishes in Saint-François-Longchamp, offering significant elevation gain for the longer formats. Registration for the 2026 edition opens on 4 December 2025 at 10:00 local time and participants are directed to the organiser’s Programme and S’inscrire pages for definitive maps, GPX files and rules. The event also includes family-focused activities such as an Animathlon for children alongside the main triathlon distances.
