Race Through History at the 45th Annual San Diego International Triathlon!

Join us on Sunday, June 27, 2027, for the San Diego International Triathlon (SDIT)—a special 45th anniversary edition celebrating one of the longest-running and most iconic triathlons in the world. With a stunning course, premium athlete perks, and an unforgettable race-day experience, this is a must-do event for every triathlete.

Why This Race Stands Out

🏊 Spectacular Course: Swim in the calm waters of San Diego Bay, bike along the breathtaking Cabrillo National Monument, and run through downtown San Diego past the Star of India and USS Midway Aircraft Carrier, finishing along the scenic waterfront.

👕 High-Performance Tech T-Shirt: A fantastically lightweight, breathable race shirt designed for athletes.
