Event: 60 Grind
101 years ago, in 1920, the Mount Lemmon Control Road was the first road constructed to access the higher, cooler elevations of the Santa Catalina Mountains. For those seeking a truly epic and memorable experience on one of the most iconic mountains in the sport of cycling, this will be the ultimate adventure! The 60 Grind course is concentrated on a 41.5-mile loop with a 9.25-mile out-and-back (18.5 miles round-trip) section for 60 miles of total riding and takes riders through sections of the Coronado National Forest and the neighboring town of San Manuel. The 9.25-mile out-and-back section comes at Aid #1 (12 miles) and offers riders an additional 2800 ft of climbing in 9 miles. There are 47.7 miles of gravel/dirt roads and 12.3 miles of paved roads. Expect little to no motor vehicle traffic. Conditions of gravel roads can vary from hard-pack to rutted or washboard depending on the last time the roads were graded and/or touched by monsoon downpours. Elevations along the course vary from 3000 ft to 8000 ft. At the lowest point of the course, average high temps are in the upper 70’s for this time of the year. We highly recommend a Mountain Bike for this course.
