Five period correct groups of legendary race cars will be featured. Each based on performance and age, competing in one-hour sessions, four times each over the 24 hours. The first group will take the green flag at noon on Saturday.

A 3 minute pit-stop during each session (driver change is optional), will be required. When one group takes the checkered flag the next group is on the grid and ready to roll out behind the pace car for their chance to race on the high banks of Daytona.

‚ÄčLeading up to this exciting event will be 3 days of Practice, Qualifying, and a Night Practice for cars competing in the Classic 24 Hour. Complementing the Classic 24 Hour will be HSR's signature Sprint Races and Endurance Series.
