Rim Rock 50 Mile Trail Challenge
The Rim Rock 50 Mile Trail Challenge is an inaugural ultramarathon held in Napa Valley, California, centered at Skyline Wilderness Park. The race features a challenging 50-mile solo course or a 50-mile relay for teams of two, traversing rugged trails through Skyline Wilderness Park, Napa Open Space Preserve, and the newly opened Suscol Headwaters Trail System. Participants experience diverse terrain including oak forests, exposed ridgelines, and panoramic valley views.
The event emphasizes environmental stewardship as a cupless race, requiring runners to carry their own hydration. Amenities include multiple aid stations, camping options, and post-race meals. The race supports local conservation efforts and the Bay Area Ridge Trail network. Visit the organization's website for the most recent information.
