Why are racetracks called downs - I know a down is English for hill but does it tie back to a specific track like Epsom Downs or some other?

Racetracks are called "downs" primarily due to the historical association with the term used in England to describe open, rolling grassland suitable for grazing. The name is famously linked to Epsom Downs, where the Epsom Derby is held, and other similar locations. The term reflects the geographical features of these sites rather than a specific track, as many racetracks in England and elsewhere are located on such downs.
