Set for its annual running this year in the San Francisco Bay Area, the Sanborn Park Trail Challenge runs feature a half marathon, 9-mile and a 4.2-mile race that take runners on an out-and-back trail run through Sanborn Skyline County Park, which looks out onto nearby Saratoga, Cupertino and San Jose from the mountains above the valley.
Runners will start the race at the park entrance visitor center just off Sanborn Road, which lies just over a 10-minute drive west from Saratoga.
From there, the course takes runners on a winding route along the nearly 3,700-acre park’s 15 miles of lushly wooded trails in the Santa Cruz Mountains, along the San Andreas, Skyline and Summit Rock Loop trails out to the half marathon turnaround point, which lies parallel to Skyline Boulevard.
