Three sports, one race — swim, bike, run in sequence, with transitions that are a discipline of their own.
Open water, open roads, and competition with yourself. Cross the finish line knowing what it took to get there.
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
