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 sections of the longest continuously used road in the country.  While our modern bike wheels may have replaced wooden wagons of days ago, traversing these rugged parts requires the same grit and sense of adventure.  On offer is an unforgettable day in the saddle of shared fun, memories, and adversity.  Let's Chino!
