Join hundreds of participants at this beloved 35-year tradition held at scenic Castaic Lake, just 20 miles north of Los Angeles, where you'll find 18 different event formats across Olympic and Sprint distances to suit every skill level—from classic triathlons to RunBikeRun, SwimBike, SwimRun, and swim or run-only options. You'll navigate a modified V-shaped swim course in Paradise Cove with lifeguard coverage, pedal through peaceful back roads, and finish with a beautiful trail run that offers stunning views of the lake, all while helping support Canyon High School's Cross Country and Track programs.
