Round of Ohio

The Round of Ohio is a current TM Master Cup event held at the Ohio Motor Speedway in Columbus, Ohio. It made its first known appearance in 2005 when Leonid Roderick won the race. In at least 2006, it was held at Mansfield Motorsports Park.

The 2013 race saw one of the biggest upsets in Master Cup history when Darren Cardel crossed the line first, being only in the race with the Promoter's Option.
