The Bike course includes some challenging climbs, while the Run course is rolling on mostly natural dirt/gravel surface with spectacular views of the lake.

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.
