Babbling streams will be your soundtrack as you challenge yourself on the lush single-track within Bothe-Napa Valley State Park. The course is a bit challenging with the hills, streams and rocks - which makes it all the more exciting and rewarding. This state park is a local treasure that is untapped by tourists and located just minutes from the area's great restaurants and wineries. The event is limited to 300 participants and sells out every year so don't wait too long to register!
NOTE: This event is in no way associated with the Annual Napa Valley Marathon (the road race).

CANCELLATIONS: Registrations are non-refundable and non-transferable. Here are the policy Terms & Conditions of the Race Roster Enhanced Refund Protection Program. You cannot purchase it AFTER you have completed your checkout. Otherwise, if you don't purchase the refund protection, and you need to cancel, you can email us by September 24, 2026 to receive a rollover credit (the amount you paid minus a $20 fee) to use toward any future Enviro-Sports race. After that date, a doctor's note is required to receive a credit.
HEADPHONES POLICY: Since parts of this race include very narrow trails with steep drop-offs along the course, it is imperative that runners can hear each other in order to pass safely, even if they are running at a slow speed. For safety reasons (and for the enjoyment of your fellow runners) headphones (and any other audio devices) are NOT allowed.
