Colorado National Speedway has been thrilling fans since 1965, when visionaries Gene & Gerta Heffley carved a one-mile dirt oval track out of a field with a spectacular view of the Rocky Mountains. Later on, CNS was a high banked half-mile dirt track before being reconfigured and paved in 1989. Since then, Colorado National Speedway has been a part of the NASCAR Weekly Racing program, and has hosted major race events such as the NASCAR Craftsman Truck Series from 1995 – 1997.

​

This summer, CNS is excited to celebrate our 60th consecutive season and continue the tradition of short track racing in Colorado with epic events: the 4th of July Winged Sprint Car Spectacular, Father's Day Super Sunday Monster Truck Show, ARCA Menards Series, CARS Tour West, Legend Summer Nationals, North American Big Rigs & more. CNS also plays host to an incredible weekly racing program featuring some of the best drivers in the Rocky Mountain Region competing regularly across 11 different divisions.
