2026 Napa Valley Trail Marathon, Half Marathon & 10K

2026 Napa Valley Trail Marathon, Half Marathon & 10K

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 Napa Valley Marathon (road race) scheduled for March 2026.
