United States Round Salt Lake City

This track was originally conceived as a novelty track for Larry H. Miller, owner of the NBA's Utah Jazz, to use as a personal playground, with a budget of about $5 million. Due to enormous local motorcycle and auto industry support the concept gradually grew into an $85 million plus project, one of a kind in the U.S.

On 22 August, 2007 Miller Motorsports Park announced a three-year deal to bring the FIM Superbike World Championship to the track; the Superbike World Championship will race at the track for the first time on 1 June 2008 with the AMA Superbike Championship. To avoid direct comparisons between World Superbike and AMA Superbike, and because of sponsorship issues the two championships will race on different configurations of the circuit. World Superbike will use the Outer course, while AMA Superbike and its support classes will use the Full course
