Query: In what direction does one travel from Richmond to reach Southside Speedway?
Context: 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.
