The City of Oceanside collaborates with IRONMAN to put on a half-IRONMAN triathlon every year. The race includes a 1.2-mile swim in the harbor, dips into Camp Pendleton for a 56-mile bike, and finishes with a 12.1-mile run along Pacific Street and the Strand. The finish line celebration is at the Jr. Seau Pier Amphitheater. The race draws in competitors from around the world in addition to local athletes. The race also features an IRONKIDS portion the day before (April 5, 2024) from 3pm-6pm, which is a short run along the Strand for children of all ages.

Please expect multiple street and parking Lot closures. The Harbor beach and launch ramp will also be closed throughout the event.
