Triathlon Terheijden 2026

Triathlon Terheijden is a Dutch triathlon held annually in the village of Terheijden, near Breda in North Brabant, on the second Sunday of June. Established in 1983, it is one of the oldest triathlons in the Netherlands. The event features eighth-distance and quarter-distance triathlons, with options for solo participants or duo/trio relay teams. The race layout is compact, with the swim, transition area, and finish line situated within approximately 500 meters. Competitors swim in the Mark river, near the Breda rowing club, and complete multiple 2.5 km laps for the run. The field comprises recreational athletes, fitness enthusiasts, and competitive racers, reflecting the character of Terheijden, a village of just over 6,000 people situated along a sand ridge beside the Mark, an area historically shaped by peat extraction, tides, dikes, and floods.
