Oceanside is proud to be the host of this world-renowned event. IRONMAN 70.3 California started out as an IRONMAN in 2000. Two years later it was turned into one of the first IRONMAN 70.3 events and helped launch the popularity of the distance.
This race offers the only chance athletes have to swim in the calm, protected Oceanside Harbor, where water temperatures in early spring are usually in the low to mid 60’s.
The bike course takes cyclists along the California coastline to San Clemente, before dropping down into the Marine Corps Base Camp Pendleton. Here, challenging hills confront athletes before they swing back to the Oceanside Pier—one of the longest fishing piers in California.
The run portion takes athletes on a winding journey along the pier, and then out to Oceanside’s flat beachfront path known as “The Strand,” where miles of sandy beaches provide a beautiful and distracting vista. Runners then turn into a residential area before looping back out for a grand finish at the ocean’s edge and a chute lined with energetic spectators.
