Enjoy a fun day at the races. The 2018 winter season at Rillito Park features 6 Fri.-Sun. weekends of live horse-racing, Feb. 10-March 18: 12 days with thoroughbred racing in the late afternoon and Quarter Horse racing under the lights at night. ( Dates are subject to approval by Arizona Board of Racing and may change .) Rillito Park (formerly known as Rillito Downs and Rillito Race Track) originally opened in 1943 and is considered the birthplace of modern, formalized Quarter Horse racing; the introduction of the "photo finish" and the straightaway “chute system,” a standard for Quarter Horse racing today, remain a part of Rillito’s legacy. No outside food or beverages are allowed in. Please, no pets. Contact the park for information about reserved table seating (520-745-5486). Rillito Racetrack is listed on the National Register of Historic Places; the 2018 season marks its 75th anniversary meet.
