Napa Wine Country Marathon Half Marathon & 10k

From the starting line at the park’s picnic area, runners in the half-marathon will run the roughly six-mile course twice, following 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. Once those running the 13.1-mile course reach the aid station back at the picnic area — the half-marathon half-way point — they turn around and run the same course a second time. Hikers and walkers welcome. There’s a 6-hour course time limit for all races, which means runners in the half marathon will need to keep a pace of 27:30 minutes per mile or faster (that’s 13:45 minutes per mile for the full marathon). So there’s plenty of time for walkers and hikers to finish the race within the official time limit.
