The Experience
The Napa Spring Half Marathon starts at Oxbow Commons Park in downtown Napa, sending runners into the rolling countryside of one of California’s most celebrated wine regions. The course winds past vineyards and wineries, offering a scenic tour of the valley with minimal elevation change—ideal for runners chasing a fast time.
The race draws about 530 runners from 22 states, with roughly one in five returning year after year. Typical spring weather brings cool temperatures in the 40s to 60s, low rain chance, and light wind. The flat course and swift winning times (averaging under 1:25) make it a prime candidate for personal bests.
The finish line returns to Oxbow Commons Park in downtown Napa, where post-race festivities and the town’s famous wine and dining scene await. With its blend of speed and scenery, the Napa Spring Half Marathon offers an inviting race-cation for runners looking to combine a PR attempt with a taste of wine country.
