Biggest Running Events and Marathons in Sonoma County

Get your run on in Sonoma County!

With its beautiful, varied terrain and extensive back-country roads, Sonoma County is a runner’s paradise. Which is precisely why so many major running events are held here throughout the year.

You’ll have a wonderful experience — running through vineyards, redwood trees, along the ocean, and almost always in sight of nearby mountains. Then you get to return home with a finisher’s medal and bragging rights.

With a mixture of flats and gently rolling hills, the course will take you amongst vineyards resplendent in fall colors, with views of the Russian River valley, with a varied terrain of paved country roads and groomed dirt/gravel country roads.

Hallowine Run

The fall-colored vineyards will glow in the warm sunshine and you’re bound to see some fun characters on the course. The Half Marathon course is very scenic and easy to medium difficulty, with gentle rolling terrain on backcountry roads, starting at Francis Ford Coppola Winery and ending at the Warm Springs Recreation Area. The Hallowine 10K starts at Francis Ford Coppola Winery and ends at Martorana Family Winery. Both the Hallowine 5K and Kids & Dogs Costume Run start and finish at the Warm Springs Recreation Area.
