Auto racing is also popular in the area. The Richmond International Raceway (RIR) has hosted NASCAR Sprint Cup races since 1953, as well as the Capital City 400 from 1962 − 1980. RIR also hosted IndyCar's Suntrust Indy Challenge from 2001 − 2009. Another track, Southside Speedway, has operated since 1959 and sits just southwest of Richmond in Chesterfield County. This .333-mile (0.536 km) oval short-track has become known as the "Toughest Track in the South" and "The Action Track", and features weekly stock car racing on Friday nights. Southside Speedway has acted as the breeding grounds for many past NASCAR legends including Richard Petty, Bobby Allison and Darrell Waltrip, and claims to be the home track of NASCAR superstar Denny Hamlin.
