About the race
Babbling streams run alongside single track trails at Bothe-Napa Valley State Park in Napa Valley, California. The event offers multiple trail distances through wooded parkland with hills, stream crossings, and rocky sections. The course is marked with orange ribbon at turns and crossings. There is one aid station at the start/finish area; half marathoners pass it once between loops and marathoners encounter it at miles 6, 10, 16, and 20. Organizers recommend that participants carry hydration.
Distances included:
- Marathon
- Half Marathon
- 10K
- 5K
The 10K is a single loop. The half marathon consists of two 10K loops. Marathoners run the 10K loop, a roughly 4-mile out-and-back extension to the Old Bale Grist Mill, repeat that sequence, and finish with a final 10K loop. A six hour course cut-off applies; published pace thresholds are provided for each distance.
Participant entries are limited to 300. Bib numbers are mailed beginning two weeks before the event; participants who do not receive a mailed bib may pick one up on race morning. All participants receive event T-shirts. Finisher medals are awarded for the full and half marathons; personalized ribbons are mailed to top three finishers by age group for each distance.
Parking inside the park requires a fee; free overflow parking is available along Highway 29. Headphones and other audio devices are not allowed on narrow sections for safety reasons. Registrations are non-refundable and non-transferable; rollover credit options may be available before February 20, 2027, subject to organizer policy.
