The track

The track opened as a 15-turn, 2.4 mile (3.86 km) road circuit run clockwise. The back portion of the track allows speeds approaching 180 mph (290 km/h). A separate starting line is located on the backstretch to allow for safer rolling starts. The regular start/finish line is located on the pit straight. In 1990, the track underwent a refurbishment. A new retaining wall was built, the entire track was resurfaced, widened, and concrete was paved in the apexes of the turns to prevent asphalt deterioration. In addition, a straightaway was paved through the chicane, allowing for two different track layouts, the original 2.4-mile (3.9 km) circuit, and a new 13-turn, 2.258 mile (3.634 km) circuit. In 1990, the CART series began utilizing the 2.258-mile (3.634 km) layout. In 2006, a second major refurbishment saw several improvements. The entire circuit was repaved, and the concrete patches in the turn apexes were removed. A new motorcycle "short course" was created by connecting turn one with the backstretch, and another motocross oval was created by connecting the chicane straight with the backstretch. The additional layouts allow simultaneous use of the multiple course, for instructional and competitive uses. The improvements also included a motocross facility, that has since been closed. There is grandstand seating for 10,000 spectators, and three observation mounds alongside the track raise the capacity to over 75,000.

History

The track was opened in 1962 by Les Griebling and several Mansfield-area businessmen as a location for weekend sports car racing. In 1982, Mid-Ohio was purchased by Jim Trueman, a renowned road racer and the founder of Red Roof Inns. Trueman added permanent grandstands, amphitheater-style seating, garages with spectator balconies, a five-story media and hospitality center, underground tunnels and an updated paddock area. In 1990, the track underwent a refurbishment. A new retaining wall was built, the entire track was resurfaced, widened, and concrete was paved in the apexes of the turns to prevent asphalt deterioration. In addition, a straightaway was paved through the chicane, allowing for two different track layouts, the original 2.4-mile (3.9 km) circuit, and a new 13-turn, 2.258 mile (3.634 km) circuit. In 2006, the track again underwent extensive renovation. The track and pit lane were completely resurfaced and connectors were added to the track's famed Keyhole section to allow for three separate road course configurations. Also completed was the removal of concrete patches from the track, the relocation of the wall and guardrail at Turn 1, the expansion of gravel traps at the exits of Turn 1 and the keyhole, the replacement of all remaining old-style catch fencing, and the standardization of curbing throughout the circuit. These changes have resulted in a faster, safer, more competitive and attractive facility for drivers, riders and race fans.

The sports car course operates from April through November each year. During this time, the facility is host for a number of nationally sanctioned race weekends, all of which are open to the public. Mid-Ohio has hosted "closed course" events for kart racing events since the late 1960s sanctioned by I.K.F. & W.K.A. and run by the Dart kart Club with up to 400 entries attending. Karts use the full track with the chicane. Additionally, on site motor home and tent camping spaces are available. The 2011 season marks the 50th in the track's storied history of racing. On March 2, 2011, it was announced that the track had been purchased from Truesports by Green Savoree Racing Promotions, which currently promotes several IndyCar street course races, ending Truesports' 29 years of ownership. On November 13, 2012, NASCAR announced that the track would hold the Nationwide Children's Hospital 200 in the 2013 season.
