It was first held as a Late Model Sportsman and Modified doubleheader in 1970, and in 1982 the Late Model Sportsman feature changed to a touring format for the original 1982 Budweiser Late Model Sportsman season, and stayed as a touring race until 1994. Following the 1994 season, both of Martinsville's race, the Miller 500 and the Advance Auto 500, were converted to Late Model only races. The March Late Model race was discontinued at the end of the 1997 season. 2201818
