Track Facts

1

Mid-Ohio is known for its flowing, narrow layout with minimal runoff areas — precision is essential, and the walls are unforgiving.

2

The circuit was built by Les Griebling in 1962 on farmland in central Ohio and has remained largely unchanged in character since.

3

The Keyhole, a sharp hairpin at the end of the back straight, is one of the most popular overtaking spots in American road racing.

4

IndyCar, NASCAR, and IMSA have all competed at Mid-Ohio, making it one of the most versatile road courses in the country.

5

The natural terrain creates significant elevation changes throughout the lap, contributing to the circuit's technical challenge.
