Join us at the birthplace of the sport for the XTERRA Wetsuits Mission Bay Triathlon!
2026 is the 38th annual XTERRA Wetsuits Mission Bay Triathlon benefitting Life Sports Foundation. San Diego is the Birthplace of Triathlon! In 1974, the first Mission Bay Triathlon was as a run-bike-swim-run event on Fiesta Island by the San Diego Track Club. Every year competitors from around the country and from around the world, come to Mission Bay to celebrate the birthplace triathlon. We invite you to become part of this wonderful legacy event and become part of history!
The event offers races for adults and kids, from complete beginners to seasoned Professionals. There are many different races going on simultaneously, and while a traditional Triathlon is Swim / Bike / Run, KOZ Events, the organizer of the San Diego Triathlon Series, offers more of a Multisport Race. Our race is very inclusive and we make triathlon accessible to as many people as possible. We have the traditional Swim/bike/ Run Triathlon but we offer so much more. If you do not like swimming, we have the Duathlon which is a Run/ Bike/ Run, if you donβt want to bike then choose the Aquathlon Swim / Run, or if you donβt want to run choose the Aquabike Swim/Bike. We even have a Mini Distance Triathlon for beginners that want to try out the sport. We even offer free training groups every week to help people get started, train, and get connected to the San Diego Triathlon Community.
