1/2 Marathon

The Napa Half Marathon is nestled up in the rolling hills of east Napa. Scenic, rustic and winding roads will take you from the start at Skyline Park through the vineyard lined neighborhoods in a charming countryside setting. Locals come out to cheer you on while curious deer are commonly seen along the course! A bottle of Napa Valley wine and a custom medal will greet you at the finish line. The race is hosted by Athletic Feat and is professionally chip timed by NorCal Timing. The Half Marathon starts at 7:30am. (Participants must be at least 12 years old on race day.)
