✅ Unrivaled Coastal Scenery
✅ The Post-Race Beach Party
The oldest 10-mile race in the United States, this event is a legendary staple of the Orange County running scene. Whether you're tackling the signature 10-miler, the 10K, or the 5K, you’re in for a high-energy morning that perfectly captures the "Surf City USA" spirit.
From the iconic starting line at the Huntington Beach Pier to the high-fives from volunteers in surf gear, this race is less of a grueling workout and more of a seaside celebration.
