The Hoosier Hundred was a USAC Silver Crown Series race held at the Indiana State Fairgrounds Speedway, a one-mile dirt oval in Indianapolis, Indiana. The race was first held in 1953, and through 1970 was part of the National Championship. It was last held in 2020. Over the years, the Hoosier Hundred was considered one of the richest and most prestigious open-wheel races in the United States. Seven winners of the Hoosier Hundred have also won the Indianapolis 500, led by A. J. Foyt, who has won six times. Therefore, the Indiana State Fairgrounds Speedway was known as the "Track of Champions."
