Founded in 1965 by Gene and Gerda Heffley, Colorado National Speedway sits at the foot of the Rocky Mountains at exit 232 off of I-25.

Each summer, CNS hosts some of the best local racing in the country; along with several national touring series, car and motorcycle shows, swap meets, and an annual Father's Day Sunday Super Show featuring Monster Trucks, Stunt Bikes, and more.

CNS is known locally for outstanding food, affordable tickets, and Northern Colorado's best fireworks display on holiday and special race events.
