👉🏼Every year the Santa Cruz Triathlon

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! 2018 and 2019 the race showed big profits, donating $70,000 back into our community! In 2021, it showed it's biggest year yet, donating $90,000 back into 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!
