Mid-Ohio Sports Car Course is a road course auto racing facility located in Troy Township, Morrow County, Ohio, United States, just outside the village of Lexington. Mid-Ohio has also colloquially become a term for the entire north-central region of the state, from south of Sandusky to the north of Columbus. It hosts a number of racing series such as IndyCar, IMSA WeatherTech Sportscar Championship, and the NASCAR Xfinity Series, along with other club events such has SCCA and National Auto Sport Association. The track The track opened as a 15-turn, road circuit run clockwise. The back portion of the track allows speeds approaching . A separate starting line is located on the backstretch to allow for safer rolling starts. The regular start/finish line is located on the pit straight. In 1990 the track underwent a refurbishment. A new retaining wall was built, the entire track was resurfaced, widened and concrete was paved in the apexes of the turns to prevent asphalt deterioration. In addition, a straightaway was paved through the chicane, allowing for two different track layouts, the original circuit and a new 13-turn, circuit. In 1990, the CART series, along with other racing series, began utilizing the layout. In 2006 a second major refurbishment saw several improvements. The entire circuit was repaved and the concrete patches in the turn apexes were removed. A new motorcycle "short course" was created by connecting turn one with the backstretch and another motorcycle oval was created by connecting the chicane straight with the backstretch. The additional layouts allow simultaneous use of the multiple course, for instructional and competitive uses. The improvements also included a motocross facility, that has since been used for the AMA Vintage Motorcycle days event. In 2019 the ARX came to the track which was the first time rallycross had come to the circuit. The course was a 10-turn, and utilized the keyhole section of the track. There is grandstand seating for 12,000 spectators and three observation mounds alongside the track raise the capacity to over 75,000. Mid-Ohio is classified as an FIA Grade Two circuit.
