Entry is limited, cutoffs are enforced, and carpoolers will receive commemorative memorabilia.

The SOCAL River Marathon is a late-winter Saturday race held at Huntington Beach State Park in Huntington Beach, California. Runners can choose from four in-person distances: a full marathon, half marathon, 10K, and 5K. The event also offers a virtual race for any distance, along with invite-only pacer entries for the marathon and half marathon. The primary route utilizes the Santa Ana River Trail, running from Yorba Linda to Huntington Beach State Park.

The course is predominantly flat and straight, featuring a slight downhill gradient as it parallels the river towards the sea.
