Utah Motorsports Campus, Racing Circuit

Utah Motorsports Campus is a permanent motorsport facility located near Grantsville in Tooele County, Utah, United States, west of Salt Lake City. Designed by motorsport architect Alan Wilson, the venue opened on 1 April 2006 as Miller Motorsports Park, a project of car dealer and racing enthusiast Larry H. Miller. Its full circuit measures roughly 4.486 miles (7.220 km) across 23 turns, making it one of the longest permanent road courses in the world. The track is highly configurable and can be divided into several shorter layouts, including outer, east and west courses, allowing multiple events to run concurrently. The complex also incorporates a karting track, a paved oval and additional driver-training and off-road areas. After the Miller family era it was renamed Utah Motorsports Campus in 2015 and has passed through subsequent ownership and operating changes. Over the years it has hosted national and international series, including AMA Superbike, FIM World Superbike and various sports car and club racing championships. The facility is widely used for professional competition, track days, driving schools and corporate events.
