The Xfinity 500 is a NASCAR Cup Series stock car race held at Martinsville Speedway in Ridgeway, Virginia. The race is traditionally held in the fall and has been run in every NASCAR Cup Series season, starting with the sixth event in the inaugural 1949 season, making it the oldest NASCAR race still run today. It is currently the ninth race of ten in the Cup Series playoffs, and the final race of the Round of 8.[2] Since 2015, NBC has held the broadcast rights for the final 20 races of the season, including this race.
