Join Us for the 2026 OC Marathon and Support Project Youth OC!
Since 2004, Project Youth OC has proudly partnered with the OC Marathon as an official Charity Partner. This year, we are celebrating 22 years of impact - and reaching a major milestone.
In 2026, Project Youth OC will surpass $1 million raised through our partnership with the OC Marathon.
Our Road to a Million campaign represents more than a number. It reflects decades of community support, thousands of runners and fundraisers, and countless young lives impacted at critical turning points.
The OC Marathon offers something for everyone:
-
5K Walk/Run: Saturday, May 2, 2026, at the OC Fairgrounds.
-
Marathon & Half Marathon: Sunday, May 3, 2026, starting at Fashion Island and finishing at the OC Fairgrounds.
When you join our team, you’ll help empower youth and strengthen families across Orange County.
Every dollar raised through peer-to-peer fundraising goes directly toward life-changing mentorship, education, and support services for over 1,500 youth and their families each year.
Together, we can run, walk, and fundraise for a brighter future!

Levels Run Club launched in Costa Mesa in July 2024 when trainer Tony Corong transformed casual friend runs into something bigger, a thriving community built on genuine welcome from day one. The crew believes progress comes in levels and everyone starts somewhere. Rooted in the philosophy that movement unlocks potential, Levels Run Club gathers runners of all backgrounds every Saturday at Focus Athletics for a dynamic warm-up and 5K run at 8:30 AM. All paces are welcome here, no exceptions. What started as informal runs became a warm, low-pressure space where real connection matters as much as the miles.
