Riverside International Raceway (sometimes known as Riverside, RIR, or Riverside Raceway) was a motorsports race track and road course established in the Edgemont area of Riverside County, California, just east of the city limits of Riverside and 50 mi (80 km) east of Los Angeles, in 1957. In 1984, the raceway became part of the newly incorporated city of Moreno Valley. Riverside was noted for its hot, dusty environment and for being somewhat of a complicated and dangerous track for drivers.
