Originally conceived as a personal playground for Utah Jazz owner Larry Miller, Utah Motorsports Campus (former Miller Motorsports Park) has instead become a thriving center for motorsports of all kinds. Opened in 2005, the facility includes a kart/autocross track, as well as a main circuit that can be used in four possible configurations, with the East and West Circuits capable of being operated simultaneously. The full circuit is a sprawling 4.5 mile course with 23 turns, but the Outer Loop is favored for professional events.
