Runners start the out-and-back course for the race’s half marathon at McNear’s Beach County Park, just outside China Camp State Park on Cantera Way. From there, runners will follow the course as it winds its way along the hillside and along the beach overlooking the bay, following an east-to-west direction through the park. Overall, the course is made up of two surfaces — some stretches takes runners along paved roads, while others are run on dirt trails.
