Chino Grinder is Arizona’s longest-running and original Gravel Grinder. It is an Ultra-Endurance cycling event showcasing multiple distances for all ages and experience levels. The course is remote and highlights Arizona’s diverse beauty while traveling on parts of the longest continuously used roads in the country. While our modern bike wheels may have replaced wooden wagons of days ago, our grit and sense of adventure remain the same. Now less traveled, these roads offer an unforgettable day in the saddle of shared fun, adventure, and adversity.
