Napa Valley Marathon and Half Marathon Runner Perks
5-★ Reviews from Runners Like You
“Second year running this and it’s high key the best event in the Bay Area! The course is beautiful and goes through wine country – you can watch the sun rise over the vineyards and the fog settle into the valleys. It’s just so scenic and incredible.”
“This is such an awesome race. It was my 4th time running it and I’m already registered to come back a 5th year. The course has such amazing views. It’s an overall downhill but has rolling hills and banking turns which give it a good challenge. Pace groups were awesome, course support was great.”
