The Summer Mile Stakes is a Group 2 race that allows horses that are at least four years old to enter, with the racing being run over a distance of seven furlongs every July.
In its beginning days, it was known as the Silver Trophy Stakes and would take place at Lingfield Park. It was in 1999 that its distance was changed and the Summer Mile Stakes transferred over to the Ascot Racecourse.
It did return to Lingfield for 2005 due to renovations at Ascot, making it the first Group race in the region to have taken place on a synthetic surface. It was in 2006 that it was renamed as the Summer Mile Stakes, with it being upgraded to a Group 2 race in 2007.
Mutakayyef and Green Line Express have both won the Summer Mile Stakes on two occasions, with Dane O’Neill being the leading jockey with four wins, including riding Mohaather to victory in the 2020 renewal.
