Kentucky Speedway Infield Road Course

Kentucky Speedway's Infield Road Course is a multi-configuration racing circuit located within the larger Kentucky Speedway oval in Sparta, Kentucky, United States. Constructed in 2005 alongside the main oval track, the infield road course offered versatility to the facility, catering to a broader range of motorsports disciplines. While the oval is primarily known for NASCAR events, the road course provides a platform for sports car racing, club events, and driver training programs.

The layout of the road course is complex, incorporating portions of the oval's banking and apron. It features a mix of tight corners, sweeping bends, and short straights, demanding a balanced car setup and skilled driving. The primary configuration measures approximately 2.37 miles in length, with other variations possible by utilizing different connector roads and chicanes. Technical characteristics include a blend of asphalt surfaces, varying camber angles, and a challenging braking zone entering the oval. The course has 14 turns.

The Infield Road Course has hosted various types of racing events, including SCCA (Sports Car Club of America) regional and national races, NASA (National Auto Sport Association) events, and other amateur motorsports competitions. It has also been used for manufacturer testing and automotive enthusiast track days. While it hasn't secured major professional-level road racing series like IndyCar or IMSA, its accessibility and challenging design make it a popular venue for grassroots motorsports and driver development.

What makes the Kentucky Speedway Infield Road Course unique is its integration within a larger oval track. This allows for a dynamic track experience, utilizing the high-speed banking of the oval for certain sections of the road course. The combined oval and infield design creates a visually distinctive and technically demanding circuit, catering to both stock car and sports car enthusiasts. The versatility of the course allows for multiple configurations, accommodating a variety of racing series and skill levels.
