Runners follow an out-and back loop course through Chabot Regional Park for the half marathon, which starts and finishes at the Lake Chabot Marina and starts runners off onto the West Shore Trail. From there, runners make their way around the lakeshore, along trails including the Cameron Loop, Live Oak, Towhee, Brandon and Logger’s Loop trails, and then finish the race near the picnic sites on the East Shore trail.
