San Diego International Triathlon

The San Diego International Triathlon (SDIT) is a multi-sport event that takes place in downtown San Diego. With a history spanning over four decades, it is one of the longest-running triathlons. The event features a variety of disciplines and distances to accommodate different athletic preferences, including triathlons, duathlons, aquabikes, and a standalone run.

The courses traverse various landmarks in the area. Participants swim in the calm waters of the San Diego Bay and ride bicycles along a route that passes Cabrillo National Monument, the Point Loma Lighthouse, and Fort Rosecrans National Cemetery. The running portion follows the waterfront, taking athletes past the USS Midway Aircraft Carrier and the Star of India ship towards the finish line.
