TUCSON, Ariz. (13 News) – A Tucson tradition that goes back 80 years, will be absent in 2024. There will be no horse racing at Rillito Park. “The bottom line is there will not be racing this year at Rillito,” County Administrator Jan Lesher told the Pima County Board on Tuesday. “We have a variety of requirements that were due to us by Rillito Racing, including an audit and a variety of things, but those things have not occurred.”
