2017 Epsom Derby

The initial entry for the 2017 Epsom Derby, announced in December 2015, consisted of 416 yearlings. The number of entries was a decrease of 59 on the initial entry for the 2016 race, and included 54 horses from the Godolphin Racing organisation and 59 from the Coolmore Stud.[2] Another 10 horses were added at the second entry stage in April 2017 at a cost of £9,000 per entry. The second entries included Thunder Snow, winner of the 2017 UAE Derby; he was subsequently routed to the US to contest the 2017 Kentucky Derby. A further entry stage took place on 29 May 2017,[3] and saw two horses, Permian and Khalidi added to the line-up after their owners each paid supplementary fees of £85,000.[4] The two-day declarations on 1 June saw the withdrawal of the outsider Finn McCool leaving a field of nineteen horses.

The most controversial entry was Diore Lia, a filly who had shown no racing ability in two starts and who was scheduled to be ridden by the inexperienced apprentice jockey Gina Mangan. After safety concerns were raised the BHA allowed the horse to take part but insisted that Mangan be replaced by a more qualified rider.[5] The filly was withdrawn on the morning of the race after sustaining a muscle injury.

Ireland staged the first notable trial for the 2017 English Derby when the Ballysax Stakes was run at Leopardstown Racecourse on 8 April and produced a considerable upset as Joseph O'Brien sent out Rekindling to win at odds of 16/1. Douglas Macarthur, Yucatan and Capri, the next three finishers, were all trained by O'Brien's father Aidan and represented the powerful Coolmore organisation.[6] The first significant British trial races took place at the Craven meeting at Newmarket Racecourse in April. The Listed Feilden Stakes over nine furlongs on Tuesday 18 saw the John Gosden trained Khalidi prevail by a neck over the betting favourite Salouen.[7] In the Group 3 Craven Stakes (primarily a trial for the 2000 Guineas) over one mile two days later Eminent (from the first crop of foals sired by Frankel) scored an upset victory over Rivet with Godolphins Benbatl in third place.[8] In the following week Epsom Racecourse staged the ten-furlong Investec Derby Trial, and in a very tight finish, Cracksman, from the Gosden stable, caught the Mark Johnston-trained Permian in the final stride to win by a short head.[9]

The 2000 Guineas at Newmarket on 6 May was won by Churchill with Eminent in sixth place. Churchill had been the winter favourite for the Derby but his connections opted not to follow the Epsom route, deciding to keep the horse to shorter distances. On the same day Permian won the ten furlong Newmarket Stakes, beating Speedo Boy by four and a half lengths with the favoured Khalidi in third place.[10] On the following day Leopardstown staged the Derrinstown Stud Derby Trial which resulted in a clean sweep for the Aidan O'Brien stable as Douglas Macarthur won in a three-way photo-phinish from his stablemates Yucatan and Capri.[11] At Chester Racecourse the following week the O'Brien domination continued with a 1-2-3 in the Chester Vase as Venice Beach won from Wings of Eagles and The Anvil.[12] Two days later at the same meeting O'Brien sent out Cliffs of Moher to win the Dee Stakes at odds of 4/5.[13] The Lingfield Derby Trial on the 13 May saw a victory for Godolphin as Best Solution, who had spent the early part of 2017 in Dubai, won by three and a quarter lengths from Glencadam Glory.[14] The Dante Stakes at York Racecourse on 18 May attracted its usual strong field and saw Permian win from Benbatl, Crystal Ocean (a highly regarded colt from the Michael Stoute yard) and Rekindling.[15] The last major trial was the Listed Cocked Hat Stakes over eleven furlongs at Goodwood Racecourse on 26 May which resulted in a five length win for Khalidi.[16]

The final field of eighteen saw seven Irish-trained challengers matched against eleven British-trained colts. Fourteen of the runners were supplied by three major stables: Aidan O'Brien (six runners), John Gosden (five) and Saeed bin Suroor (three). The only female jockey was Anastasia "Ana" O'Brien who became the third woman to ride in the race after Alex Greaves and Hayley Turner.[17]

Diore Lia was number 19 on the card, drawn 17, but was a non-runner.

The race took place in fine, sunny weather on a surface officially described as "good". On the morning of the race Cracksman and Cliffs of Moher were disputing favouritism but by race time Cracksman headed the betting on 7/2 with Cliffs of Moher on 5/1 alongside Eminent. The best-supported of the other runners were Permian (8/1) and the inexperienced Dubai Thunder (9/1). When the race began, the Aidan O'Brien-trained Douglas Macarthur went to the front ahead of his stablemate The Anvil, and the pair quickly opened up a lead of several lengths over the rest of the field. As the field turned into the straight, Douglas Macarthur still led from The Anvil, Venice Beach, Best Solution and Cracksman, whilst Cliffs of Moher, Eminent and the 40/1 outsider Wings of Eagles were towards the rear. The Anvil and Venice Beach dropped back but Douglas Macarthur maintained his gallop and briefly went clear of the field before being overtaken by Cracksman approaching the final furlong.[18] The favourite was soon challenged as both Cliffs of Moher and Eminent made strong late challenges and Wings of Eagles made rapid progress from the rear. Cliffs of Moher headed Cracksman in the closing stages but was in turn overtaken by Wings of Eagles who won by three-quarters of a length. Cracksman held on for third ahead of Eminent with a gap of three and a half lengths back to Benbatl in fifth.[19] Wings of Eagles was the longest-priced winner of the race since Snow Knight triumphed at 50/1 in 1974.[20]
