Willow Springs International Motor sports Park is a 600-acre complex of eight racetracks embracing nearly every conceivable motor sports discipline. The park is located about an hour north of Los Angeles, California near Lancaster. The original track at the facility, Willow Springs International Raceway, celebrates its 55th birthday this year, and is steeped in historical significance. Construction of the track began in 1952, with the inaugural event held on November 23, 1953. The fact that it has been running continuously since then has caused the state of California to recognize Willow Springs International Raceway as an Official California Point of Historical Interest. This world-famous track hosted the first two NASCAR events west of the Mississippi, the first F.I.M. 500 Grand Prix motorcycle race in America, the first AMA events, the first 24-hour motorcycle endurance race, the first kart road racing in America, and the first California Sports Car Club racing on a purpose-built road course. Over the years, track records have been set and broken many times by internationally famous drivers and riders. Willow Springs International Motorsports Park also includes the following facilities: Willow Springs Raceway (2.5 mile road course); The Streets of Willow Springs (a 1.8-mile road course); Walt James Stadium (3/8 mi Clay Oval and Paved Oval); Willow Springs Speedway (a lighted 1/4-mile paved oval), Willow Springs Kart Track (a .625-mile, 9-turn paved sprint track); The Balcony (a 1/4-mile paved autocross and drifting track); Horse Thief Mile (1-mile canyon road course with many elevation changes and tight corners); and approximately 160 acres of off-road, mountainous terrain.
