The Race

The Course

Located near the banks off scenic Possum Kingdom Lake lies a 4,000 acre private ranch that serves as the backdrop for the 2022 Hidden Hills Ultra. Settled by one of the original families to the area, this unique ranch hosts lake views, mountains, cedar and oak forests, and rocky terrain. You'll run almost entirely on ranch roads. The out and back course will follow a route made up of rock, dirt, and rolling terrain.

NOTE: The Palo Pinto Mountains State Park is currently under construction. Due to the popularity of this Hill Country race as part of our Texas Trail Running Eco Series, we are excited to announce that we are able to move this race to a nearby, beautiful private 4,000-acre ranch, next to Possum Kingdom Lake, in Graham, Texas for the 2022 race.
