Sebring International Raceway was originally a World War II airbase used to train B-17 combat crews. It is America’s oldest road racing track, with over 6 decades of history. Renowned for its rough track surface, the course still runs on old sections of the concrete landing field. Host to the 12 Hours of Sebring, the facility consists of three tracks: the Full Circuit, the Modified Circuit, and the Short Circuit. For 1 and 3 Day Racing Schools, we utilize the 9-turn 2.0-mile Modified Circuit. For the 2 Day Advanced Racing School, we utilize the 17-turn 3.7-mile Full Circuit.
