Churchill Downs, pictured here, is one of the most famous race tracks in the United States. The mile race course opened in 1875 but is not the oldest. That honor goes to Saratoga Race Course in Saratoga Springs , NY which was established in 1863. Horse racing has been around longer than basketball and football and at one time in the 50’s & 60’s it’s annual total attendance was greater than all sports, even baseball.
