SOCAL River Marathon - 26.2 - 13.1 - 10K - 5K 2027

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. It crosses a significant portion of Southern California, beginning in arid inland areas, passing near Disneyland, and concluding at the beach. The course is predominantly flat and straight, featuring a slight downhill gradient as it parallels the river towards the sea.
