Road Closures


Dear Neighbor,

Sunday May 5, 2019 – for the running of the 15th Anniversary OC (Orange County, CA) Marathon. We hope you look forward to this day with a sense of pride, as the Orange County community will once again be on display for runners from around the country and the world to see.

You have not disappointed in the first 14 years of the event. The runners greatly appreciate the enthusiasm you have shown as they pass through your neighborhoods – the cheering, the candy and fruit, the colorful balloons, the cool mist from a garden hose – all great gestures that make this event so wonderful.

We understand the race impacts your routine for a few hours on a spring Sunday, but we’d like to share with you the positives aspects of the race of which you may not be aware. Did you know that in 2016, over $5 million was pumped into the Orange County economy as a result of the race? Did you know that the event has also generated more than $5 million for charity? Local charities such as Susan G. Komen, John Wayne Cancer Foundation, and the OC Bar Foundation, to name a few, have all benefited from the event.

Did you know that the OC Marathon Foundation heads up one of the largest youth running programs in the nation? The Kids Run the OC was in 136 Orange County Schools, with over 9,000 kids in 2017 and we expect to have 10,000 kids in 2018 and be in over 140 schools.

As we make plans for this year’s race, we would welcome any input from you so that the event has a positive impact on your community.

Thank you.


The event will be held on Sunday, May 5, 2019. Road closures and delays will begin starting at 4:00 a.m. throughout our host cities of Newport Beach, Santa Ana and Costa Mesa, lasting in some areas through 3:00 p.m.
