IRONMAN 70.3 Oceanside

April 4, 2020

Oceanside is proud to be the host of this world-renowned event. IRONMAN 70.3 Oceanside 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.

They’re putting the “ocean” back into Oceanside! You get to experience the ocean and the harbor as they will be having a beach start and finish at the boat ramp inside Oceanside Harbor. You’ll get a chance to have a practice swim and then your friends and family will be able to “Hang Ten” with you til your time corral starts.

The bike route portion of the event starts from Oceanside Harbor thru Camp Pendleton & San Onofre Bluffs State Park, continuing thru Trestles onto Cristianitos overpass and back onto Camp Pendleton’s Cristianitos gate. Then there’s the rolling hills on your bike that occur prior to San Mateo hill following by two more nice hills only to come upon a flat but very windy road to wind back at the Oceanside Harbor.

The run portion is a two looper and is considered flat and fast but be prepared for the turns and inclines/declines as you go from beach level to street level. The two-loop, 13.1-mile run course begins at Transition above the Oceanside Pier, down onto the Harbor, on The Strand and through coastal neighborhoods before a spectacular finish.
