From the starting line at the Bothe-Napa Valley State Park picnic area just outside Calistoga, runners in the half-marathon will run the roughly six-mile course twice. After leaving the starting line, they follow an out-and-back loop route along the park’s Coyote Peak Trail, South Fork Trail, Ritchey Canyon Trail and Redwood Trail, running alongside the waters of Ritchey Creek for much of the early and later parts of the race.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
