Flanders Triathlon Sports 2026

Flanders Triathlon Sports is a multi-disciplinary race event in Haacht, Belgium, scheduled for a Friday in July. It is built around triathlon formats, but it also offers paved running and endurance options, with distances listed from 5 km and 10 km up to a half marathon, 24 km, 84.2 km, and 300 km. Participants can choose 1/8, 1/4, and 1/2 triathlon formats, plus a double triathlon equal to two Ironman-distance races. The event also includes a 24-hour race and two children’s categories, Mini-kort and Mini-lang, so the same programme covers kids, standard-distance triathletes, long-distance runners, and extreme endurance athletes.
