Utah Motorsports Campus

Utah Motorsports Campus is a permanent road racing facility in Grantsville, Utah, just west of Salt Lake City near the town of Tooele. Opened in 2006 and originally known as Miller Motorsports Park, the circuit sits against the high desert backdrop of the Oquirrh Mountains and has long ranked among the most ambitious purpose-built tracks in North America. Its full configuration stretches 4.486 miles across 23 turns, making it one of only four permanent racing circuits in the world with an official minimum length of at least 7 kilometers.

The site is designed as a flexible, multi-configuration campus rather than a single fixed circuit. The full course can be split into shorter East, West, and Outer layouts, giving organizers and instructors a range of track lengths and corner counts to work with. Wide runoff, long straights, and a varied mix of fast sweepers and technical sections make it a favorite for high performance driving instruction, club racing, and professional test programs alike.

Over the years the venue has hosted a deep slate of national series, including the American Le Mans Series, ARCA Menards Series West, MotoAmerica Superbike, Porsche Sprint Challenge, and Formula Drift, plus the trademark time trial stage of the Tour of Utah bicycle race. For drivers, the combination of elevation, generous sight lines, and reconfigurable layouts makes Utah Motorsports Campus an exceptional place to build speed and car control, which is exactly why it remains a premier destination for racing schools and track day programs.
