Come enjoy the beauty of Orange Country Triathlon California. Triathletes and Relays begin with a 1500 meter swim in the calm waters of Lake Mission Viejo. After leaving transition, bike 40 kilometers up and down scenic Santiago Canyon, finish the bike ride just outside of Mission Viejo at transition 2. From there, you’ll begin your 10K run back to your friends and family at the Lake. The event also features a Duathlon, which subs out the 1500 meter swim for a 2K run, an aquabike, which skips the run, and a 5K run that starts and finishes at the Lake.

Each participant receives a premium souvenir shirt or sweatshirt, a finisher medal and a meal ticket.
