Runners follow an out-and-back trail at the Trail Quake Half Marathon along the trails that wind through Sanborn County Park, which lies near both the Santa Cruz Mountains and about 50 miles southeast of San Francisco. The half marathon takes runners along the San Andreas Trail that winds through the park, and then heads back to the starting line area for the race finish.
