Track Information
In 2007, the Clay County Fair Association debuted a newly reconstructed 3/8 mile clay track on the Clay County Fairgrounds. The previous track was a large, flat, half-mile oval that was generally used for horse racing. In order to host high-quality auto racing events, the fair deemed it necessary to construct a completely new racetrack. It was converted to a 3/8 mile clay track, with increased corner banking to adjust for the higher speeds of auto racing. Additionally, a state-of-the-art lighting system was installed to make the races more visible for both drivers and fans.
