  The Santa Cruz Triathlon is a popular, scenic, non-profit race offering Sprint and International (Olympic) distances, plus relays, aquabike, and an aquathlon option, known for its coastal course along West Cliff Drive and along Highway 1. Its an ocean swim around the iconic Santa Cruz Wharf, a spacious transition area on a soccer field, then riding out along West Cliff and Highway 1 to the quaint town of Davenport and back. Then finish with a beautiful run along West Cliff and finish on Cowells Beach.

  This is great for beginners and veterans alike, with proceeds funding local high school and college athletics in Santa Cruz County. It's a long-running event that donates significantly to youth sports, featuring a sheltered ocean swim and largely closed-course bike and run, creating a fun, community-focused event.
