Runners follow an out-and-back course that winds along the trails of Huddart Park just outside Redwood City at the Woodside/Purisima Creek Crossover Half Marathon, which starts and finishes near the Werder Picnic Area inside the park. From there, runners follow a series of trails around the northern and western edges of the 973-acre park, including the Chapparal, Crystal Springs, Richards and Skyline trails, before heading back to Werder for the race finish.
