Battle of the Fenders Canceled December 5-6, 2025

To our Drivers, Crews, Fans, and Employees - we hate to announce that the 9th Battle of the Fenders 300 is canceled for this weekend - as is practice for today. The forecast for Wednesday called for 1" of snow, and we got 6".

COLORADO NATIONAL SPEEDWAY

AFFORDABLE FAMILY FUN AT COLORADO'S ONLY NASCAR TRACK

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. Check out our event schedule to find out what is upcoming, and grab your tickets to experience a thrilling night of action at Colorado's premier NASCAR short track, Colorado National Speedway!
