The NASCAR Sprint Cup Series' 36 championship-points events are held at 23 tracks in 20 states. All told, from the weekly and regional levels to the three national series, NASCAR sanctions more than 1,500 events in 11 series at 110 tracks in 37 states, Mexico and Canada.
The Sprint Cup Series in particular has made recent efforts to expand west. Four tracks opened in a 10-year span (1988-98) in California (Sonoma, Fontana), Nevada (Las Vegas) and Arizona (Avondale) during NASCAR’s westward push. In addition to California, Florida (Daytona, Homestead-Miami) and Virginia (Martinsville, Richmond) have multiple tracks.
The oldest track currently on the Sprint Cup Series is Martinsville Speedway, which hosted its first race in 1949. The newest? Kentucky Speedway, which had its first Sprint Cup race in 2011.
In addition to Kentucky, two other tracks (Chicagoland Speedway, 2001; Kansas Speedway, 2001) have opened since the turn of the century.
