Sebring International Raceway is North America’s oldest sports car racing facility, originating from a WWII B-17 training base known as Hendricks Field. Since 1952, the third weekend in March has seen the world’s best cars and drivers compete on the grueling 3.74-mile Sebring circuit, a mixture of concrete and asphalt surfaces, racing into the Florida night with the scent of orange blossoms filling the air.
