Napa Valley Marathon and Half Marathon
The Lowdown
The Napa Valley Marathon and Half Marathon send runners point-to-point down the world-famous Silverado Trail through the heart of Napa Valley wine country, with mile after mile of bucolic vineyards and a gentle net-downhill grade. The marathon starts on the Silverado Trail in Calistoga and the half marathon near Conn Creek Winery; both finish at Vintage High School in Napa. A USATF-certified Boston Qualifier with consistently cool early-March weather, the event is a favorite of both first-timers and competitive runners. A Kiwanis Club of Greater Napa 5K is also offered. Registration for the next edition opens June 24, 2027 at 8 AM PT; each distance typically sells out, so early sign-up is encouraged.
