From the Organizer
The Giant Acorn Triathlon Festival features Olympic and Sprint distance races staged out of beautiful Lake Anna State Park. With a sandy beach time trial start, a refreshing (low 70’s) freshwater swim, rolling country roads for the bike and a run course that stays completely within the State Park. The race is amazing for so many reasons, but the best part is the park itself with a beautiful venue and banked stadium style seating overlooking the swim course, run course and finish line! Bring the family as the park features miles of trails, a playground, swimming beach and visitors center featuring a “gold mine”. Outside the park you can relax post race at the Lake Anna Winery or the Coyote Hole Cider Works. Be sure to race with friends and make some new ones at the Giant Acorn Triathlon Festival.

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.
