CONCORD, N.C. — The World of Outlaws NOS Energy Drink Sprint Car Series is coming back to Colorado.
A date has been added to the 2026 schedule at Calhan, CO’s El Paso County Raceway on Monday, Sept. 14. The Rocky Mountain Rumble is set to mark the state’s first time hosting The Greatest Show on Dirt in a decade.
The most recent visit came in 2016 when the tour debuted at El Paso County. Colorado is home to 36 past World of Outlaws races spread across a trio of tracks – Colorado National Speedway (21), Rocky Mountain National Speedway (14), and El Paso County Raceway (one).
The added action will follow a Kansas weekend in the plains with returns to Belleville High Banks (Sept. 11) and Dodge City Raceway Park (Sept. 12) in store before the trip to Colorado.
Then the country’s best Sprint Car drivers will journey across the Rocky Mountains bound for a two-week west coast visit with the tracks to be announced at a later date.
