Built in 1962 as a location for weekend sports car racing, Mid-Ohio is often called the most competitive road course in the United States. The circuit is set on 330 acres in the rolling hills of Lexington, Ohio, and features a permanent road-racing circuit with two primary track configurations: a 2.4-mile, 15-turn circuit or 2.258-mile, 13-turn layout. The venue has hosted the SCCA National Championship Runoffs on several occasions.
