Formerly named the Santa Cruz Sentinel Triathlon, the Santa Cruz Triathlon is a non-profit event. Each year the race donates $30,000 to $50,000 to the Santa Cruz community! Proceeds from the event are donated to the Santa Cruz County High School athletic programs, the UC Santa Cruz Swim Program, Cabrillo College Athletics, Santa Cruz Track Club, and the Santa Cruz Triathlon Association. These organizations receive donations from the race and provide volunteers on the course. Everyone’s participation is greatly appreciated!

Named by as one of the “Top Ten Most Scenic Triathlons” in California, 2010


SWIM (1.5K) A brisk ocean swim around the Santa Cruz Municipal Wharf. Water temperature is usually in the mid to upper 50’s, so wetsuits are strongly recommended.

BIKE (40K) A challenging out-and-back ride via West Cliff Drive and coastal Highway 1. The turnaround is located in the historic coastal town of Davenport.

RUN (10K) A flat and fast out-and-back course along the ocean on beautiful West Cliff Drive.
