Triathlon de Belfort

2025 Edition — 1st Triathlon du Lion

The first edition of the Triathlon du Lion brought together over 1,400 triathletes on May 17 and 18, 2025, on the shores of Lake Malsaucy in Sermamagny. This new format was an immediate success, confirming the public's and athletes' appetite for a quality triathlon in this natural Belfort setting.

The four formats offered — Race L (La Gueule du Fauve), Race M (La Rugissante), Race S (La Coup de Patte), and Kids Races — allowed athletes of all levels, from 6-year-olds to experienced triathletes, to have an intense and friendly sporting experience. The swimming in the calm waters of Malsaucy, the cycling through the Southern Vosges landscapes, and the 100% nature run around the lake were unanimously praised by the participants.
