The event is part of the Castle Triathlon Series, six weekend triathlon festivals in stunning iconic venues and with distances for all levels from first timers to elites.
Chantilly provides a fantastic and challenging race, with the 2.5km Grand Canal overlooked by the Château and its gardens hosting the open-water swim. Triathletes will transition within the Terrasse des Connétables and set off into a fast 20km or 45km cycle circuit around the Forêt de Chantilly. After entering T2, competitors will run the surrounding woodlands, the world famous race course “LHippodrome” and Chateau gardens finishing within sight of the beautiful Chateau.
