Mid Ohio Sports Car Course

The Mid-Ohio Sports Car Course stands as one of America's premier road racing facilities, located in the rolling countryside near Lexington, Ohio. Since opening in 1962, this challenging circuit has tested the skills of world-class drivers across multiple racing disciplines. The 330-acre facility combines technical complexity with natural terrain features, creating a demanding yet beloved venue that has become a cornerstone of American motorsport.

Track Configuration and Technical Specifications

Mid-Ohio offers two primary track configurations. The full layout measures 2.40 miles (3.86 km) with 15 turns, while the modified version spans 2.258 miles (3.634 km) with 13 turns by bypassing a chicane. The 13-turn configuration is used by major professional racing series, while the 2.4-mile layout serves motorcycles and amateur club racing. The FIA Grade Two circuit features significant elevation changes throughout its layout. The back straight allows speeds approaching 200 mph (320 km/h), contrasting sharply with technical sections that demand precision and patience. The track received a complete repaving in late 2023. More recently, in late 2024 and early 2025, significant safety improvements focused on Turn 4 at the end of the backstraight. The banking of Turn 4 was reduced from approximately four degrees to two degrees. The runoff area, known as "China Beach" and historically a site of notable incidents, was reshaped, filled, and brought level with the racing surface. These modifications included extensive excavation, new underdrains, aggregate base, and high-performance asphalt to match the 2023 repavement. New curbing, drainage improvements, and modernized safety barriers and fencing were implemented in three areas around the circuit.

Signature Track Sections

Several distinctive sections define Mid-Ohio's character. "Thunder Valley" presents a challenging downhill straight that tests driver nerve. The "Madness" section consists of a roller-coaster series of esses requiring precise car placement. The "Keyhole" hairpin turn provides a critical overtaking opportunity, while the "Carousel" - a near-360-degree turn - examines both mechanical grip and driver commitment. These varied elements combine to make Mid-Ohio one of the most balanced road courses in the United States.

Historical Development

Les Griebling and local Mansfield businessmen founded the track in 1962, initially as a 16-turn clockwise circuit. After its first year, they removed the "Oak Tree Bend" section for being excessively slow. The facility underwent significant modernization in 1982 when Jim Trueman, founder of Red Roof Inns, purchased the property. In 1990, the entire track was resurfaced and widened, and a straightaway was paved through the chicane, creating the two distinct layouts in use today. Extensive renovations in 2006 included a complete repaving of the circuit and pit lane, removal of concrete patches in turn apexes, and the addition of connectors in the Keyhole section to allow for three separate configurations, including a motorcycle short course. In March 2011, Green Savoree Racing Promotions acquired ownership, continuing the circuit's development while maintaining its classic character.

Modern Facilities and Events

The facility features grandstand seating for 12,000 spectators, with open areas that can accommodate over 75,000 fans. Strategic observation mounds give spectators excellent vantage points around the circuit. Current infrastructure includes garage facilities, a media center, hospitality suites, and an operations tower. Annual headline events include the Honda Indy 200 (NTT IndyCar Series), IMSA WeatherTech SportsCar Championship, NASCAR Craftsman Truck Series, and MotoAmerica. The circuit also hosts numerous amateur and regional club events through organizations such as SCCA and National Auto Sport Association (NASA). The Mid-Ohio School operates on site, offering driving and riding programs from teen defensive driving to high-performance and professional racing instruction, utilizing Honda vehicles.
