Race details

Perfect for the adventure-minded athlete who wants to feel small while moving through nature. After a small loop through the Rosario Resort neighborhood, athletes experience the teeth-chattering bay for a short swim, a quick but potent reminder why the course uses the island’s lakes and does not swim from one San Juan island to another! The real star of this course are the unrelenting trails that either go Up Up Up or Down Down Down. You’ll need to come into race day fit and prepared for the full 12-rounds but you’ll be rewarded throughout with epic views of the San Juans Islands, the Olympic Mountains and even neighboring Canada!
