Lake Padden Park

Swim, mountain bike and trail run at the Bellingham Off-Road Triathlon. The course includes an 800-meter freshwater swim in Lake Padden, 9K of challenging mountain bike single track, and a 4.1K trail run along the lakeshore through lush forests and big trees. This is a true Pacific Northwest adventure in a race. The race can be done solo or as a relay team. New for 2023, the Bellingham Off-Road Triathlon is USAT sanctioned!
