This endurance cycling event highlights Arizona’s diverse beauty while traveling on sections of the longest continuously used road in the country.  The remote course has multiple distances suitable for all ages and experience levels, and draws a vibrant, diverse community united by a passion for gravel riding.

Chino Valley is a rural, ranching and agricultural community approximately 10 miles north of Prescott Valley, Arizona.  Known as ‘Big Sky’ country based on its endless views in every direction, Chino Valley sits at around 4,700 ft.  Although you won’t find the iconic saguaros most commonly associated with the Arizona desert, the surrounding rolling hills are blanketed in golden Gama grasses where native Pronghorn roam.
