Runners start the out-and-back course for the ZombieRunner Halloween Half Marathon at Hellyer County Park in San Jose, California, which lies just a short drive south from downtown San Jose. From there, runners head south onto the Coyote Creek Trail to Metcalf Park and back, along which they’ll run mostly on paved surfaces and some stretches of dirt roads and single-track trails.
