The Chino Grinder is a classic-style gravel road cycling event started in 2014. The course is designed to test each riders strength, speed and especially their endurance, featuring a variety of terrain and surfaces. The route follows the Overland Historic Road Trail, the oldest continuously used road in the United States (since 1000 AD) from Chino Valley Arizona to Whitehorse Lake near Williams Arizona before returning to Chino. Participation is limited to 600 cyclists. This is a gravel bike course, there is nothing technical about it. What makes it difficult is the climbing and change of altitude, elevations range between 3800 feet to 7300 feet.
