Paddington will bid to register a fourth Group One in a row when he takes on Inspiral in Wednesday’s Qatar Sussex Stakes at Goodwood.

Aidan O’Brien’s Paddington began the season in handicap company but has progressed to win the Irish 2,000 Guineas, the St James’s Palace Stakes and the Coral-Eclipse.

His most recent victory came over 10 furlongs but he will drop back down to a mile this week to take on John and Thady Gosden’s three-time Group One winner.

Inspiral was beaten by Triple Time on her only outing to date this season in the Queen Anne at Royal Ascot, but will be looking to give Frankie Dettori another big win in his final season.

A field of six has been declared with William Haggas’ Aldaary, Richard Hannon’s Chindit, Roger Varian’s Charyn and the French challenger Facteur Cheval completing the line-up.

Royal Ascot winner Big Evs faces off against Karl Burke’s speedy Kylian in a fascinating clash in the Jaeger-LeCoultre Molecomb Stakes.

Big Evs, trained by Mick Appleby, was a surprise winner of the Windsor Castle Stakes but there did not appear to be any fluke about his three-length success, while Kylian has won his last two races by an aggregate of 10 lengths after two short priced defeats earlier in the season.

Hannon’s Baheer and Clive Cox’s Shagraan are also among a field of eight.

Sixteen fillies and mares have been declared for the Group Three Whispering Angel Oak Tree Stakes.

Leading contenders include the Karl Burke-trained Fast Response and Jumbly from Joseph O’Brien’s yard.

Paddington’s rate of improvement compares to nothing Aidan O’Brien has seen before as his three-time Group One scorer attempts to keep his winning streak going in the Qatar Sussex Stakes.

The son of Siyouni has won six races on the bounce and having started the season winning a heavy ground Naas handicap has progressed to become one of the standout three-year-olds of the season.

Having landed the Irish 2,000 Guineas in May, he quickly asserted himself as the leading miler of the Classic crop when taking the St James’s Palace Stakes at Royal Ascot, before stepping up in trip to down Emily Upjohn in a thrilling renewal of the Eclipse.

Now the outstanding Ballydoyle colt returns to the eight furlongs over which he made his name at the Qatar Goodwood Festival and O’Brien believes his rise to the top has no equal during his long and distinguished training career.

He said: “What he has done has been incredible. He’s gone from strength to strength with every run and it is very unusual.

“I know Ryan (Moore) is very impressed with him all the time and he looks a very serious horse at the moment. I think he’s standing up to a lot of scrutiny by the other horses that have gone by before him.

“It’s very unusual what he is doing and the ease with which he is doing it and the way he is doing it.

“It’s very hard to compare him but I’m not sure we’ve ever had a horse that has made that improvement in the way he is doing it, mentally, physically and confidence-wise and everything really. He just looks so natural.”

Having seen off Emily Upjohn over 10 furlongs at Sandown, Paddington could have another John and Thady Gosden-trained star filly to tackle on the Sussex Downs in the form of Inspiral, who the bookmakers feel has the best chance of knocking Paddington off track.

It will be the first time he will have faced older horses over a mile, but the master of Ballydoyle is eager to see a competitive contest so he can get a true feel for Paddington’s potential accomplishments.

“We always treat every horse with total respect, but we’re also delighted when the races are as competitive as they can be because that is what we all want to see,” said O’Brien.

“That is what we need to gauge our horses and know where we are going next.

“The more competitive it is and the better the horses are that are in there, the better it is for us and everyone else, we think.”

There will be a continental flavour to the Qatar Sussex Stakes next week as French raider Facteur Cheval is set to take his chance in the red-hot Goodwood contest.

It will be a long journey to the Sussex Downs for the four-year-old, with trainer Jerome Reynier based near Marseille in the south of France.

However, having produced a career best when denied by a head in the Prix d’Ispahan in May, connections are keen to pick up a share of the £1million prize-fund on offer, en-route to their main objective for the second half of the campaign, the Woodbine Mile on September 16.

“Our main goal for the fall is the Woodbine Mile and we needed something to tick him over,” said Barry Irwin, CEO of Team Valor, who own the gelding in partnership with Gary Barber.

“We know this is going to be an insurmountable task, but the timing is right and he is improving, so we are going to send him and see what happens.”

Facteur Cheval has won five of his 10 career stars with his biggest victory coming in the Prix Perth on his final outing last year.

Although he has failed to add to his tally this season, the son of Ribchester has held his own in three high-class events and connections retain plenty of faith in Facteur Cheval, who will be partnered for the first time by Maxime Guyon in the Qatar Goodwood Festival contest.

“Obviously we’re probably going to be running against Paddington and you can’t go into it thinking we’re going to win,” added Irwin.

“But we’ve got a lot of faith in this horse, he’s had a lot of bad luck and we’re hoping we’re going to get a better go of it this race.

“He’s going to be ridden by Maxime Guyon and he has a lot of ability. He just needs the space to run in, once he gets going he’s pretty good.”

Irwin hopes Facteur Cheval will fare better than Star Of Cozzene, who was sent to the Sussex Stakes in the early 1990s in search of testing ground and found the undulations of Goodwood too hot to handle.

“I ran a horse there in the same race in 1992 called Star Of Cozzene,” he added. “He was one of the best horses we have ever had.

“He was fantastic over here in America and I got the bright idea to send him to Europe because he loved heavy ground. He never won a race there, he placed a couple of times but it just never happened.

“When we ran him at Goodwood, he had never run without toe wraps before and he just slid down the hill, he must have been 25 lengths off the lead at one stage and ran sixth. So I know what a difficult place Goodwood is.”
