Sebring International Raceway, Racing Circuit

Sebring International Raceway lies in Highlands County in central Florida, close to the city of Sebring and sharing its site with the regional airport. The circuit was laid out across the runways and connecting roads of Hendricks Army Airfield, a World War II base that trained B-17 bomber crews between 1941 and 1946, and it opened at the end of 1950. What began as a temporary affair has become a permanent, year-round facility and one of the oldest continuously operating circuits in the United States. The 3.74-mile, 17-turn course is famous for its surface: large stretches retain the original wartime concrete runway sections, with around 0.7 miles of concrete amid the asphalt, producing the notoriously bumpy character that punishes cars and drivers alike. Since 1952 it has hosted the 12 Hours of Sebring, one of the cornerstones of international sports car racing and a round of the IMSA WeatherTech SportsCar Championship. In recent years the venue has also staged the FIA World Endurance Championship's 1000 Miles of Sebring on the preceding day, drawing the world's leading prototypes and GT cars. The bumps, the heat and the long night make the 12 Hours one of endurance racing's sternest tests. Beyond its marquee weekend the track is used for testing, historic racing and driving schools. Sebring endures as a mecca for sports car enthusiasts worldwide.
