Mid-Ohio Sports Car Course is a road course facility located just outside the village of Lexington, Ohio. The track is a 15-turn, 2.400 mi (3.862 km) road circuit run clockwise. The track was opened in 1962 by Les Griebling and several Mansfield-area businessmen as a location for weekend sports car racing. The track originally had 16 turns, with a left turn in what is today known as "thunder valley," but the turn was straightened after just one year of operation due to complaints of the track being too slow. 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, tunnels and an updated paddock area. There is no doubt Mid-Ohio is one of the premier race tracks in America and hosts every conceivable road racing series.
