Runners start the out-and-back course for the half marathon at the boat launch just off Wueste Road at Lower Otay Lake, which lies about a half-hour’s drive from nearby San Diego. From there, they make their way along the trails that wind along the shoreline of the lake, and run along the western edge of Upper Otay Lake before heading back along the western side of the lower lake on the way back in to the race finish line at the boat launch.
