OC Marathon Runners Take Over Newport Beach, Costa Mesa Sunday

NEWPORT BEACH (CBSLA) — The 17th Anniversary OC Marathon takes places this Sunday, so motorists should be aware of several street closures through Newport Beach, Costa Mesa and other parts of Orange County.

The OC Marathon usually takes place in May, but was rescheduled to November due to the ongoing pandemic. Runners will take off from Fashion Island at 6 a.m. and run a route that will take them along Newport Bay, into Newport Beach, past John Wayne Airport, into Santa Ana, south along the 405 Freeway, and veering around to finish at the OC Fair and Events Center.
