"[1] The American Road Race of Champions (ARRC) began in 1964, as a non-championship round of the SCCA National Sports Car Championship.
[5] In July 2013, the SCCA announced, in a break from tradition, that the Runoffs would begin to move around venues across the country annually, similar to other major sporting events such as golf's U.S. Open and the NFL's Super Bowl.
First up in 2014 was a return to the west coast and first time visit to Mazda Raceway Laguna Seca, which became just the seventh track to host the Runoffs.
The event then alternated to the east coast in 2015 and visited Daytona International Speedway for the first time since 1969 before heading back to Mid-Ohio Sports Car Course in 2016.
For 2020, the Runoffs returned to Road America to continue the annual rotation of East, Midwest, and West.
