The OC Marathon & Half Marathon Weekend

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.
