Light on Tri Madine - M 2026

Light on Tri Madine is a September triathlon weekend held at Lac de Madine in northeastern France, featuring the M race as a central part of the program. The M format is a standard-distance triathlon: 1.5 km swimming, 40 km cycling, and 10 km running. It is offered alongside shorter S and longer L options, allowing the same event site to accommodate newcomers, younger participants, and athletes seeking a more extensive challenge. The race begins at the lake, with the swim naturally preceding the bike leg and concluding with the run. The weekend also includes a Long Distance format, comprising 1.9 km swimming, 90 km cycling, and 21 km running. The S race consists of a 0.5 km swim and 5 km run, with a shorter cycling segment. Julien Labdant is the listed race director, and participants are directed to Light on Tri for registration and practical information.
