One of the toughest triathlons in the world is coming to town. Whistler will host Subaru Ironman Canada this summer with the race course incorporating its beautiful lakes, mountain roads and the Valley Trail Network. The race will start with a 2-loop swim in the clean shallow waters of Alta Lake. Athletes will enjoy a lakeside transition before starting a 1-loop bike course via the Sea-to-Sky Highway, Callaghan Valley & Pemberton. The 2-loop course will utilize the Valley Trail, winding past Lost Lake & Green Lake before a triumphant finish adjacent to Whistler Olympic Plaza.
