The Race

The Course

Located near the banks of scenic Possum Kingdom Lake lies a 4,000 acre private ranch that serves as the backdrop for the 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.
