The initial entry for the 2015 Epsom Derby, announced in December 2013, consisted of 409 yearlings.
The number of entries was three more than for the 2014 race and included 71 from Godolphin Racing and 54 from the partners of the Coolmore Stud.
Sheikh Fahad Al Thani's Qatar Racing organization entered 15 yearlings while Sheikh Joaan bin Hamad bin Khalifa Al Thani was responsible for 12 entries.
Amongst the Coolmore entries was a colt who had been purchased for a record public auction price of 3.6 million guineas in October 2013, and other owners with significant numbers of entries included Aga Khan IV with 51 yearlings and Sheikh Hamdan Al Maktoum's 47 entries.
The number of potential runners was reduced to 102 at the first scratching date in March 2015, with John F Kennedy heading the betting market at odds of 6 to 1.
The Coolmore stable was left with 21 possible runners, including John F Kennedy and the record auction colt, now named Sir Isaac Newton.
A further 12 horses were added at the second entry stage in April 2015, including Gleneagles and Elm Park.

The field began to take its final shape on 22 May when sixteen horses were left entered at the final forfeit stage.
Amongst those remaining in the race were Gleneagles, who had won the 2000 Guineas since being entered; Hans Holbein, the winner of the Chester Vase and Jack Hobbs, runner-up in the Dante Stakes.
The betting market was headed by Golden Horn, winner of the Feilden Stakes and the Dante Stakes, but who was not yet entered in the Derby.
Golden Horn's owner, Anthony Oppenheimer, had indicated that he would enter the horse at the supplementary entry stage.

Final confirmations for the race took place on Monday 1 June leaving a potential field of fifteen runners.
Gleneagles, Great Glen and Prince Gagarin were withdrawn by Aidan O'Brien and Golden Horn was supplemented as expected at a cost of £75,000.
Success Days, winner of the Ballysax Stakes and Derrinstown Stud Derby Trial, was also supplemented for the race.
The filly Found and Sumbal had been considered by their connections for supplementary entries but were not entered.
Golden Horn was the favourite in the betting market at this point at odds of 7–4, followed by Zawraq at 5–1, Jack Hobbs at 7–1 and Elm Park at 9–1.
The other eleven runners were all listed at 10–1 or greater.
On the Tuesday before the race Zawraq returned from a gallop with a minor leg injury and his participation in the Derby was put in doubt.
Zawraq's odds moved out to 7–1 while Giovanni Canaletto's price moved in to 8–1 after Ryan Moore was announced the horse's jockey for the race.
On Thursday Zawraq was found to be lame again and was withdraw at the final declaration stage that morning along with Best Of Times and Rocky Rider, leaving a final declared field of twelve runners for the 2015 race.

On the day of the race, Saturday 6 June, Epsom's clerk of the course, Andrew Cooper, moved the Going description to "good, good to firm in places".
The going for Friday's racing at Epsom had been "good" but dry weather that afternoon and overnight had made parts of the course good to firm.
Jack Hobbs' participation in the race awaited a decision from trainer John Gosden, dependent on his view of whether the going would suit Jack Hobbs.
After the first race of the afternoon the going description was changed to "good to firm",  despite which Jack Hobbs was allowed to take his chance in the race.
