The Mid-Ohio Sports Car Course is a classic road circuit on the outskirts of Lexington. It is used by a variety of prominent US motorsport series, and is relatively fast with a selection of challenging corners. Since its establishment it has been continuously upgraded, and from 2006 has included a short circuit for motorcycle racing, and a motocross oval. Three grandstands line the circuits, providing a spectator capacity of 75,000.

The facility has hosted a variety of championships, including the American Le Mans Series and IndyCar Series, and can be split into two separate layouts. The complex also houses a driving school, which offers safety training and circuit testing.
