The event is a 100 kilometer loop through the Wasatch Mountains above Provo, Utah, with a start/finish area near Springville and Right Fork Hobble Creek Road.

The surface composition is listed as 48% dirt trail, 44% dirt road, and 8% paved. Total elevation gain is over 15,000 feet with a corresponding loss of about 15,000 feet.
