RIBCHESTER and Churchill stand their ground in Wednesday’s Qatar Sussex Stakes, the £1 million mile showpiece, which has attracted a final field of nine and forms part of the QIPCO British Champions Series.

William Buick has acclaimed triple Group 1 winner Ribchester as the horse with the highest cruising speed he has ridden ahead of the colt attempting to cement his position as Europe’s top miler.

The jockey is wary of the challenge Ribchester faces in conceding 7lb to Churchill, the QIPCO 2000 Guineas victor.

Before his surprise reverse at Royal Ascot, when he started at 1/2, Churchill had won seven races in succession - four of them at the highest level. Aidan O’Brien, his trainer, remains puzzled by his subdued effort at the Royal Meeting, but has suggested that an extremely hot day in Ireland and England, with travelling in between, might have been a factor.

Churchill bids to become the ninth QIPCO 2000 Guineas winner to go on and win the Sussex Stakes in the same season since 1945. The past three to do so have been Rock Of Gibraltar (2002), and Henrythenavigator (2008) - both trained by O’Brien - and the mighty Frankel (2011).

O’Brien is also represented by Lancaster Bomber, who finished a length second to Barney Roy in the Queen Anne Stakes, having previously finished behind Churchill the five previous occasions they had met.

Zelzal, who had Zonderland well adrift when winning the Group 1 Prix Jean Prat at Chantilly last year, flies the flag for France. The last French-trained winner was Solow in 2015.

The field is completed by Toscanini, deployed as a pacemaker for Ribchester last time, and Here Comes When.

William Buick said. “Ribchester has yet to take on the three-year-olds this year and we go there with plenty of respect for Churchill. His defeat in the St James’s Palace seemed a big shock to his team, and you only have to go back to Newmarket to see what he is capable of.

“A dual 2000 Guineas winner? You don’t take them lightly and I certainly don’t underestimate him. He gets the weight and he’s a big horse, a strong horse. The weight concession is massively in their favour [three-year-olds in general] and from this time of the year onwards they are maturing all the time.”

Buick has been on board for his two Group 1 wins this term, and he said: “He used to be a bit immature, very energetic, and it was hard to channel it in the right direction all the time. Now he’s really matured and he has turned into top-class horse.

“Richard and his team have done a fantastic job with him. A lot of it is down to them that he is so adaptable in a race. He seemed to enjoy it from the front at Newbury but, equally, he can come from behind. He has got the highest cruising speed of any horse I’ve ridden and he can quicken off it as well, which is a great asset for a miler.”

In last year’s Qatar Sussex Stakes, Ribchester finished with a flourish after having to wait for a run and was beaten a neck and a short head in one of the best finishes of the season. At the time, Buick was suspended and had to watch from the sidelines.

“He was a bit unlucky 12 months ago, but he was not the finished article then,” he said. “Even so, it was still a very good performance - he nearly ran down The Gurkha and Galileo Gold.”
