Introducing the Rim Rock Trail Challenge – 50 Miles of Grit, Glory, and Napa’s Wildest Terrain
Be part of history in the making! The first-ever running event on the newly opened trails of the Soscol Headwaters Park in Napa Open Space is here—and it’s not for the faint of heart.
The Rim Rock Trail Challenge isn’t just another ultra. With 50+ miles and a punishing 12,800 feet of elevation gain, this course will rank as one of the toughest 50-milers in Northern California. It’s raw, rugged, and relentlessly beautiful.
Whether you’re:
• Stepping up your game
• Training for your first 100-miler
• Or simply craving a true backcountry challenge…
This is your proving ground.
