OC Marathon, Half Marathon & 5K

Sunday, November 7, 2021 • Newport Beach, CA • Course Map

Note: The full marathon is on pause for 2021.

A gorgeous, scenic course that unfolds through the Southern California coastal communities of Newport Beach and Costa Mesa awaits at the OC Marathon, Half Marathon and Wahoo 5K & Kids Run, which saw more than 14,000 runners, walkers, wheelchair and hand crank competitors cross the finish line last year.

Just down the shore from Huntington Beach and Long Beach here in the greater Los Angeles area, the race begins next to Newport Beach’s Fashion Island shopping center. From there, runners in the half follow the same route as the full marathon for most of the half marathon route, starting first with the first mile southward along the Pacific Coast Highway to the Corona del Mar neighborhood.

Runners next follow Narcissus Avenue and then Ocean Boulevard westward along Corona del Mar State Beach, where they can look out in the distance toward the waves of the Pacific Ocean making their way onshore.

The course then winds its way in a roughly northwest direction along the waters of Beacon Bay, taking runners along Bayside Drive and then back onto the Pacific Coast Highway for a brief out-and-back stretch over the bridge that crosses over the bay into the Bay Shores area, and then wind their way northward for the next stretch of the course, which takes runners north toward Upper Newport Bay.

Runners stay on Galaxy Drive for the next few miles, winding their way along the road with the Upper Newport Bay over their shoulders. After passing the mile 11 marker at the top end of Upper Newport Bay, runners then cross over onto University Drive/Del Mar Avenue and then Santa Ana Avenue, and then again back onto Mesa Drive.

The final mile of the half marathon then winds through residential neighborhoods along both Santa Ana Avenue and Mesa Drive, passing by the Santa Ana Country Club and its golf course as they hit the home stretch toward the finish line at the Orange County Fairgrounds.

The course time limit for the half marathon is 3 1/2 hours — and it’s open to walkers, organizers point out, adding “as long as you can walk a 15-minute mile, you can walk the half marathon.”
