Track Facts
Sebring was built on a WWII Army Air Corps training base — parts of the original concrete runways are still used as the track surface today, making it one of the bumpiest circuits in motorsport.
The 12 Hours of Sebring is the oldest sports car endurance race in America, first held in 1952.
The unique surface makes tire and brake management absolutely critical — teams spend hours studying data to predict degradation.
Ferrari, Porsche, Jaguar, and Ford have all built legendary rivalries across Sebring's decades of history.
Night racing at Sebring is iconic — the combination of darkness, bumps, and dust makes it one of the most challenging stretches in endurance racing.
