🌊 RACE THROUGH SAN DIEGO
This isn't a race tucked away on the outskirts of town. SDIT puts you right in the middle of San Diego.

Start your morning on the waterfront at San Diego Bay and race through a course filled with some of the city's most recognizable scenery and historic landmarks.

🏊 SWIM — SAN DIEGO BAY
Begin your race with an open-water swim in the waters of beautiful San Diego Bay.

🚴 BIKE — POINT LOMA
Ride through Point Loma past incredible San Diego landmarks, including Cabrillo National Monument, the historic Point Loma Lighthouse, and Fort Rosecrans National Cemetery.

🏃 RUN — SAN DIEGO WATERFRONT
Finish with a spectacular waterfront run past San Diego icons including the Star of India and USS Midway, before racing toward your downtown San Diego finish line.

There aren't many triathlons where the course itself feels like a tour of the city.

Coming to watch someone race the triathlon? Don't just spectate — join the fun!

The 5.6K Waterfront Run (3.5 Miles) is a great way for family members, friends, runners, and walkers to be part of the SDIT experience.

Your family and friends can experience race morning with you, take on the beautiful San Diego waterfront course, and meet you at the downtown finish-line celebration.

It's 5K+ — because we couldn't stop the fun at exactly 5K. It's actually 5.6K / 3.5 miles!

🍺 CELEBRATE AT THE FINISH — AND SUPPORT A 45-YEAR TRADITION
Crossing the finish line is only the beginning of the celebration.

Stick around for live music, our race expo, massages, mimosas, and the Modern Times & Ashland Seltzer Beer Garden on the San Diego waterfront.

And there's an important reason the Beer Garden has been part of SDIT for so many years.
