Napa

Napa's race calendar runs through vineyards instead of city blocks — the Napa Valley Marathon follows a net-downhill, point-to-point course along the Silverado Trail into Napa, and is recognized as one of the country's top Boston-qualifying marathons. The Napa Fall Wine Country Marathon and Half Marathon add a second full-distance option each October, and wine-themed races like the Artesa Wine Run 5K and the Napa-to-Sonoma Wine Country Half Marathon lean into the valley's main industry as much as its running culture. It's a smaller, destination-style calendar, built around a handful of marquee point-to-point courses rather than a deep weekly schedule.
