Mostahdaf, Paddington and Kinross are among the big names declared for what promises to be an enthralling afternoon for Qipco Champions Day at Ascot on Saturday.

The John and Thady Gosden-trained Mostahdaf leads nine contenders for the Qipco Champion Stakes, in which the five-year-old will be bidding for a third consecutive Group One win having landed the Prince of Wales’s Stakes over the 10-furlong course and distance back in June before adding the Juddmonte International at York to his tally.

However, connections have expressed concerns about the likelihood of testing ground in Berkshire and he could yet bypass the race.

The Champion Stakes field also features last year’s winner winner Bay Bridge and third-placed My Prospero while French raider Horizon Dore is the favourite after winning each of his last four starts.

Frankie Dettori teams up with King Of Steel on what is set to be his final afternoon of European action before embarking on international engagements and an eventual move to America.

He now rides 2000 Guineas victor Chaldean for Andrew Balding in the Queen Elizabeth II Stakes after Inspiral was taken out, in what promises to be another intriguing one-mile clash.

The Aidan O’Brien-trained Paddington beat him nearly four lengths in the St James’s Palace Stakes at Royal Ascot and he seeks a fifth Group One win after his unbeaten run came to an end at the hands of Mostahdaf at York.

Tahiyra adds further spice, with Dermot Weld’s filly having won the Irish 1,000 Guineas, Coronation and Matron Stakes on her last three starts.

Nashwa runs over a mile instead of tackling the Champion Stakes, with Big Rock and Facteur Cheval both leading contenders for the French.

The Dettori-ridden Kinross faces 14 in defence of his British Champions Sprint title, although Commonwealth and July Cup hero Shaquille is a notable absentee in the six-furlong contest.

The Qipco British Champions Fillies & Mares Stakes has 14 contenders, with Free Wind another likely favourite for Dettori, who also rides Trawlerman in the opening Qipco British Champions Long Distance Cup.

The two-mile affair is the only Group Two on the card but it has drawn a quality line-up with Trueshan bidding for a fourth win in the race for Alan King, although he will have to contend with last year’s Gold Cup winner Kyprios and Lonsdale Cup scorer Coltrane in a field of eight.

Giavellotto will head to Qipco Champions Day or be put away until next season after connections shelved the idea of having a tilt at this year’s Melbourne Cup.

A narrow winner of the Yorkshire Cup in the spring, Marco Botti’s stable star has since finished fifth in the Goodwood Cup and third in the Lonsdale Cup back at York last month.

Given Giavellotto’s preference for a sound surface, a trip to Australia appeared an attractive proposition – but with the stringent veterinary checks required to contest the Flemington showpiece seemingly a factor, he will not contest the ‘race that stops a nation’ in early November.

“He’s in good form and has come out of the race at York in fine shape, but we’re not going to Australia,” said Botti.

“There were a few niggling problems and it’s not going to happen this year unfortunately. He’s fine, but there were concerns we might get him there and he wouldn’t be able to run or whatever, so we just decided bypass it for this year.

“Hopefully next year if we still have him and everything is going well then we can think about it as the Melbourne Cup is a race the owners would love to go for, and the race and the track would suit him as he seems to go on left-handed tracks.”

With the Melbourne Cup ruled out, the only viable option left for Giavellotto this season is the Qipco British Champions Long Distance Cup on October 21, but the prospect of demanding conditions at Ascot is an obvious concern.

“We’ll keep an eye on the weather as he will only go to Ascot if the ground is not too soft. Good to soft is fine, but he wouldn’t want to run on anything softer than that,” Botti added.

“If he doesn’t go to Ascot we’ll just put him away for the winter.

“We haven’t discussed plans for next year with the owners yet. I wouldn’t rule out going back to Dubai World Cup night for the Gold Cup, but let’s see how he winters and how he is after a nice break.”
