Coroebus (horse)

Coroebus began his racing career in a novice race (for horses with no more than two previous wins) over seven furlongs on good to firm ground at Newmarket Racecourse on 13 August. Ridden by William Buick he started favourite and won by one and a quarter lengths from Saga after taking the lead approaching the final furlong.^[8] In the following month at the same track the colt was stepped up in class and distance for the Group 2 Royal Lodge Stakes over one mile and started the 85/40 favourite against six opponents. After taking the lead three furlongs out he opened up a clear advantage but began to struggle in the closing stages and was caught in the final strides by Royal Patronage who won by a neck.^[9] Charlie Appleby commented "He'll have learned plenty today. We've been pleased with him at home and he's a beautiful-looking horse. I think he's just got a bit lonely out in front there in the end. He only had one run under his belt and got picked up by a horse who has had plenty of racing now".^[10]

On his final appearance of the year, Coroebus started 4/5 favourite for the Group 3 Autumn Stakes over one mile at Newmarket on 9 October when the best fancied of his nine opponents were Dubai Poet and Imperial Fighter. After being restrained by Buick towards the rear of the field Coroebus moved up to take the lead approaching the last quarter mile and won "comfortably" by two lengths.^[11] After the race, Appleby said "He's a horse who has always been exciting – even in the spring he was doing stuff he shouldn't have been doing for the size of him. He's always impressed us at home – I could have run him in May if I'd wanted to ... He wouldn't want much further than a mile. If anything, when he strengthens up he'll get quicker."^[12]

For his first run as a three-year-old Coroebus contested the Group 1 2000 Guineas over the Rowley Mile at Newmarket on 30 April and went off the 5/1 third choice in the betting behind his stablemate Native Trail and the Irish-trained Luxembourg. The other twelve contenders included Royal Patronage, Perfect Power, Point Lonsdale (Futurity Stakes), Light Infantry (Horris Hill Stakes), Lusail (Gimcrack Stakes) and Berkshire Shadow (Coventry Stakes). With Buick riding Native Trail, Coroebus was partnered by James Doyle. Royal Patronage set the pace, with Coroebus being restrained towards the rear of the field before making rapid progress approaching the last quarter mile. He gained the advantage a furlong from the finish and stayed on well to win by three quarters of a length from Native Trail with Luxembourg a further length and a half away in third place.^[13] After the race Doyle commented

He travelled incredibly strong throughout. Around the two something joined me quite quick and I just asked him a couple of questions going into the Dip and he responded incredibly. He hit the line great and showed a potent turn of foot. It forced my hand early. If that didn't happen I could have afforded to be even cheekier and he would have won even more impressively.^[14]

On 14 June at Royal Ascot Coroebus started the 10/11 favourite for the St James's Palace Stakes over one mile on good-to-firm ground, with his ten rivals including Angel Bleu, My Prospero (Heron Stakes), Lusail, Berkshire Shadow and Maljoom (Mehl-Mülhens-Rennen). After racing just behind the leaders as Lusail set the pace, Coroebus looked unlikely to obtain a clear run in the straight before breaking through on the inside rail. In a closely contested finish he gained the lead inside the final furlong and kept on well to win by a head from with My Prospero, Majloom and Mighty Ulysses a short head, a neck and a head away in third, fourth and fifth.^[15] William Buick commented

it was one of those races where it was tricky ... He travels extremely strongly and you just want him to drop his head. In the straight I had no option to go until there was enough room, and then he picked it up and went through. He's got everything you could ask for in a racehorse.^[16]

Coroebus died on 4 September 2022 during the Prix du Moulin de Longchamp race at Longchamp Racecourse in Paris, France. The horse stumbled and fell 1+1⁄2 furlongs from the finish as jockey William Buick moved him out from a pack of horses to challenge for position entering the home straight. Coroebus, who was favourite to win the race, suffered a fatal injury. Buick was unharmed.^[17] Charlie Appleby paid tribute to the horse the following day, saying "It is very sad to see a great horse, who gave so much to racing, lose his life in this way. Everyone took a lot of joy from his victories in the 2,000 Guineas and at Royal Ascot.".^[18]
