Thonon Triathlon

Le Triathlon de Thonon is a single‑day community triathlon scheduled for Sunday 28 June 2026 in Thonon‑les‑Bains on the shores of Lac Léman. The event is presented by the Leman Triathlon Club and marketed as a charitable, volunteer‑run edition with €2 from each bib donated to the Fonds Sport Santé SIRHô des Hôpitaux du Léman. The course is described as an "édition historique entre lac et montagnes", emphasising the scenic lake‑and‑mountain setting and the associative, volunteer spirit that runs the event.

The race offers two main formats — Format S (Sprint) and Format M (Olympic) — each available for individual competitors and relay teams. Format S is listed as 750 m swim, 20 km bike and 5 km run, while Format M is listed as 1500 m swim, 36 km bike and 10 km run, with the M course notably crossing the Domaine de Ripaille. Registration is open via the organiser’s Eventicom page and competitors are directed to the event site and the official regulations for licence, pass and medical/cancellation rules.
