The 4th annual Mt Lemmon Gravel Grinder is on Saturday, October 27th and features 40/50/60 mile options on one of southern Arizona's most historic gravel roads established in 1920. The MLGG is concentrated on a 40 mile loop with an out-and-back section for the 50 & 60 mile courses. The routes take cyclists through the lush, semi-desert landscape that skirt the lower elevations of the Santa Catalina Mountains and leads the way to the main climb up the backside of Mt Lemmon. The course consists of a mix of gravel/dirt and paved roads that wind its way through sections of the Coronado National Forest and through the neighboring town of San Manuel. Along the way, you'll pass through local cattle ranches and former mining operations while traveling across several cattle guards, over small narrow bridges, and through dry river beds known as washes. Incredible views of the San Pedro River Valley and Galiuro Mountain Range, a sky island mountain, can been seen from virtually anywhere along the course. The route can be done on a cross, gravel or mountain bike. Family friendly fun rides and Kids race are also available to include Bike & Gear Expo, Camping, Music, Food & Refreshments!
