It hosts a number of racing series such as IndyCar, IMSA WeatherTech Sportscar Championship, along with other club events such has SCCA and National Auto Sport Association.

After only one year, the "Oak Tree Bend" series of turns (in the northeast corner) was removed due to being too slow.

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.

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, tunnels and an updated paddock area.

In addition, a tall, three-sided scoreboard tower was constructed in the infield, strategically placed such that it was visible from nearly all spectator areas around the track.

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.

The track continued to host IMSA GT until 1993, and would not return until 2000 with Grand-Am Rolex Sports Car Series.

In addition, some observers felt that the powerful Champ Cars had "outgrown" the narrow, winding course, citing a lack of passing and competition over the previous several years.

The race has also featured support series such as the Road to Indy, Global Mazda MX-5 Cup, and Stadium Super Trucks.

As of August 2024, the fastest official race lap records on the Mid-Ohio Sports Car Course are listed as: Founded in 1993, The Mid-Ohio School offers licensed drivers and motorcycle riders programs in defensive driving, high performance driving and performance track riding programs.

Participants test their newly refined skills in the controlled environment of the facility's Vehicle Dynamics Center and on the track.
