The Sebring raceway in Florida started life as a US Army base. After the war an engineer thought it would be a good idea to hold a race similar to the Le Mans 24 hour, a sportscar endurance race. Firstly they introduced a 6 hour race, however in 1952 this was increased to the 12 hours of Sebring which is still a major part on the motorsport calender today. The track was originally just over 5 miles long, however in the 1980s it was shortened slightly and in 1996 was changed to the current layout. One of the main benefits of this meant that they could use the track and airport at the same time ‚Äì meaning it could be used a lot more.
