Formula F at the SCCA National Championship Runoffs, Single-seater racing class in the United States.

Formula F at the SCCA National Championship Runoffs is a class for open-wheel, single-seat race cars, first contested at the Runoffs in 1969 at Daytona International Speedway. The inaugural race had 21 drivers, and Skip Barber won and set the fastest lap, driving a British Formula Ford such as a Merlyn, Lotus or Royale. The class has since appeared at various Runoffs venues, not at Road America.

The race format started in 1969 at Daytona International Speedway and grew into a major event for formula racing in America. The Runoffs tradition became the pinnacle of amateur motorsport competition in the country.

The class debuted at the 1969 Runoffs at Daytona with 21 drivers, and Skip Barber won and set the fastest lap in a British Formula Ford car. Dave Weitzenhof holds the record with four wins, all at Road Atlanta. The Swift DB1 took ten victories and ten straight poles from 1983 to 1992.

Drivers need to understand the strict technical requirements, as engines must be built to specific standards. Arriving early gives competitors time to familiarize themselves with the track before racing begins.

Swift Engineering has established itself as a dominant force in this racing format with numerous victories. This shows how specialized car manufacturers shape the outcome of the competition.
