The Challenge — Three Triathlons in One!

Triathlon de Menthon — Le Défi, Trois Triathlons en un ! returns for its second edition with an innovative, Super League‑inspired short‑format challenge. The event stages three consecutive mini‑triathlons, each comprising a 350 m swim, a 10.2 km bike and a 2 km run, and offers entry as a solo competitor or as a team of three. The format emphasises repeated short efforts and rapid transitions, creating an intense, fast‑paced competition distinct from traditional single‑race triathlon formats.

Racing takes place on the lakeside at Lac de Menthon beside the Château de Menthon in Menthon‑Saint‑Bernard, offering a scenic late‑summer setting noted for its autumn colours. Registrations are stated to open very soon on the official event site, with fuller schedule and registration details to be published by the organisers ahead of the 6 September 2026 race day. The event is promoted as a compact, spectator‑friendly spectacle in a prominent local setting.
