Welcome to HASC

High Altitude Sportriders Club is a community based non-profit organization for motocross riders that maintains a premier closed-course off-road motorcycle riding facility in Grand County, Colorado. Our mission is to promote safe and fun two-wheel motorized recreation to the youth, adults, and families of Grand County and the riding public at large.

We are centrally located in Granby, Colorado and accessible to Summit, Routt, and Jackson Counties. Featuring the hilliest terrain of any track in Colorado (including Thunder Valley), High Altitude MX has numerous repeated elevation differences of a 125 ft. in very short distances. All our jumps are in harmony with the naturally hilly terrain and are designed to maximize the safety of all ages and skills. This spring, summer and fall come enjoy Colorado’s most interesting and picturesque MX track!
