Triathlon de la Madeleine - XL 2026

The Triathlon de la Madeleine XL centers on a substantial mountain bike segment: approximately 100 km with 3,400 m of elevation gain in the Maurienne valley of the French Alps. Held annually since 2015 in the Saint-François-Longchamp region, it caters to athletes seeking alpine passes alongside swim-bike-run competition. The route directs participants over well-known cycling ascents, such as the Lacets de Montvernier, the Col de la Croix de Fer, and the extended climb to the Col de la Madeleine. Originating as a tourism initiative with Idée Alpe managing operations, it later introduced an XL-3800 version before transitioning to the L-3400 format following an edition shortened due to heat. The event draws triathletes, strong cyclists, and mountain-pass enthusiasts aiming for a demanding challenge rather than a quick, flat race.
