Willow Springs International Motorsports Park is located in Willow Springs near Rosamond and Lancaster, California, and is about an hour north of Los Angeles. It is a historic race track, in existence more than fifty years. Construction of the track began in 1952, with the inaugural first race held on November 23, 1953. The main track is a challenging 2.5-mile (4.0 km) long road course that is unchanged from its original 1953 configuration. The interesting elevation changes and high average speeds make it a favorite of many road racing drivers.
Willow Springs International Raceway Park also features other racing facilities such as The Streets of Willow (1.8 mile road course), The Horsethief Mile (road course), Willow Springs Speedway (1/4 mile paved oval), Willow Springs Kart Track (a .625-mile, 9-turn paved sprint track), The Playpen (a 1/4-mile paved training track), and the Walt James Stadium (Clay Oval and Paved Oval).
