About the Event

The 2026 Napa Fall Wine Country Marathon, Half Marathon, 10K, & 5K returns to Calistoga in California on October 24th. The race begins at Bothe-Napa Valley State Park, a hidden gem nestled just minutes from the heart of wine country. Known for its lush single-track trails and natural beauty, this park offers runners stunning scenery as they challenge themselves over varied terrain.
On race morning, expect crisp autumn air with temperatures ranging between 12.5°C to 25°C, making it comfortable but still invigorating. The atmosphere is serene; the only sound will be babbling streams that provide a soothing soundtrack amidst the hills and forests. With limited space for just 300 participants who sell out each year, this event stands as a testament to its unique appeal.
Course-wise, the race offers both adult and youth distances over challenging single-track trails within Bothe-Napa Valley State Park. For those venturing on foot or half-marathon routes, the terrain includes hills, streams, and rocky paths that add excitement while testing your endurance. The marathon route stretches across 42 kilometers of firm yet slightly soft ground under moderate UV conditions.

About Calistoga

Learn more about the host city, Calistoga.

Calistoga is at the north end of the Napa Valley in the Bay Area region of California. Calistoga was founded as a hot springs resort in the 1860s by Sam Brannan, California's first millionaire, and has long been a destination for its natural hot springs and mineral water and their supposed health benefits. Its position at the north end of the Napa Valley also makes it a gateway to Sonoma County wine country. Calistoga is a visitor's destination that celebrates being different - franchise fast food is against the law (really!) and healthy hedonists are celebrated. Go wine tasting, have a fabulous dinner, then take a bike ride and have a mud bath before you leave.
