The 1.53-mile Lime Rock track was originally conceived of in 1956 by Jim Vaill, who, along with John Fitch and Cornell Aeronautical Laboratory, built the track utilizing state-of-the-art road and highway safety principles of the time. The first race, a mix of G-Production class and an MG class, was held on April 28, 1957. The winner of the G-Production was Ted Sprigg in an Alfa Romeo Giulietta. The winner of the MG class was Charles Callanan in an MG TC. In 1959, Lime Rock hosted the Little Le Mans race, won by Charles Callanan and Roger Penske in a Fiat Abarth. In 2008, the track was re-paved and two new corner complexes were added.
