Join Redwood Trails Alliance on Sunday, September 20, and help make the Moore Creek Grasshopper an unforgettable day of riding in the Napa Valley!

We’re looking for volunteers to support the event in several roles:

Aid station support at PUC Forest, the top of Dan’s Wild Ride, and the Moore Creek Park parking lot
Course marshals at key intersections—some locations require hiking or biking to reach
Morning setup before riders arrive
Afternoon breakdown and cleanup after the event

Whether you can help for a few hours or spend the day with us, your support will keep riders safe, fueled, and on course while helping raise funds for more trails and better trails at Moore Creek Park.

Come be part of a fun day, support the local trail community, and experience the Moore Creek Grasshopper from behind the scenes!

More trails, better trails!
