The Sprint Cup Series races at 22 tracks, of which only Martinsville was part of the sanctioning body’s first season in 1948.
Fonty Flock won the first NASCAR-sanctioned race at Martinsville, a July 4 event that featured mostly Modifieds and included NASCAR founder and president Bill France Sr. among the drivers. He finished eighth.
The track opened in 1947 – a year ahead of NASCAR’s birth – with just 750 seats. Now, there are 65,000 seats. NASCAR’s premier series began racing twice yearly at the track in 1950.
