The Epsom Derby is widely accepted as the biggest Flat race in the world and generally takes place at Epsom Downs racecourse in Surrey on the first Saturday in June. The 2019 race takes place on Saturday June 1 with a start time of 1630 BST.
The fourth Classic of the British season after the 1000 Guineas, the 2000 Guineas and the Oaks, the 12-furlong race is also the second part of the vaunted Triple Crown - which also includes the 2000 Guineas and St Leger. This treble was last completed by the mighty Nijinsky back in 1970.
The Epsom Derby is limited to three-year-old colts and fillies but is dominated by the former with the latter often running in the Oaks on the previous day.
The month before the Derby is littered with trials for the big race, including the Dante Stakes at York, the Chester Vase, the Lingfield Derby Trial and the Derrinstown Stud Derby Trial which is held at Leopardstown in Ireland.
338 yearlings were entered for the 2019 race back in 2017 for just £560 each, but the owner of any horse supplemented for the race at the final entry stage must fork out £85,000.
Hughie Morrison’s Telecaster - who won the Dante Stakes - and Aidan O’Brien’s Sir Dragonet – winner of the Chester Vase - were both supplemented for the 2019 running.
