About this event
One of the longest-running triathlons in the country, the Mission Bay Triathlon returns for its 38th year and hosts the USA Triathlon State Championships, with sprint and other distance options plus a standalone San Diego 5K. The calm, protected waters of Mission Bay make it a favorite for first-time triathletes, while the championship designation draws competitive age-groupers chasing state honors. Expect a large, festive field, a well-organized transition, and a waterfront finish. Register online in advance and review the athlete guide for wave starts and transition rules; arrive early for body marking and setup. Wetsuit-friendly conditions and relay options are typically offered.
