Mt Lemmon Gravel Grinder p/b Pinal County

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 an extremely challenging and memorable experience on one of the most iconic mountains in the sport of cycling, this will be a huge slice of Lemmon adventure! The 50 Grind course is concentrated on a 41.5-mile loop with a 3.75-mile out-and-back (7.5 miles round-trip) section for 50 miles of total riding and takes riders through sections of the Coronado National Forest and the neighboring town of San Manuel. The 3.75-mile out-and-back section comes at Aid #1 (12 miles) and offers riders an additional 1000 ft of climbing in 3.5 miles. There are 36.7 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 6000 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, however, you won't be alone if you choose to challenge yourself and the terrain on a drop bar Gravel Bike.
