Infineon Raceway is a 1,600-acre racing facility that hosts major racing events and provides a year-round motorsport complex.
The raceway hosts major Nascar events such as the Nascar Sprint Cup Series 3-Day and 2011 Big O Tires Racing Season. The Infineon Raceway road course features more than 160 feet of elevation change from its highest to lowest points.
The course is kept clean partly through 3,000 sheep provided by Rocky Mountain Wooly Weeders, that help maintain the facility's grasses and fire lanes.
In addition, Infineon Raceway houses the Jim Russell Racing Drivers School, a karting center and a drag racing track.
