The British Classics are five long-standing Group 1 horse races run during the traditional flat racing season. They are restricted to three-year-old horses and traditionally represent the pinnacle of achievement for racehorses against their own age group. As such, victory in any classic marks a horse as amongst the very best of a generation. Victory in two or even three of the series marks a horse as truly exceptional.

The Derby Stakes, also known as the Derby or the Epsom Derby, is a Group 1 flat horse race in England open to three-year-old colts and fillies. It is run at Epsom Downs Racecourse in Surrey on the first Saturday of June each year, over a distance of one mile, four furlongs and 10 yards, or about 1½ miles. It was first run in 1780.
