Mid-Ohio sports car course
The Mid-Ohio Sports Car Course, in the East of the USA, ranks among America’s premier road racing facilities. It is a 13 turn circuit, consisting out of a blend of fast, medium and slow speed corners, one long straightaway and has some several intimidating elevation changes. The two signature corners - the Keyhole and the near-360 degree Carousel - provide additional challenges for the drivers.
