Officials for England's premier race meeting, Royal Ascot, will roll out the red carpet for Able Friend should the world's equal-highest rated horse do as expected and win Sunday's Champions Mile at Sha Tin.

Trainer John Moore said a trip to Royal Ascot to take on Europe's best in the Queen Anne Stakes is contingent on a win in this weekend's HK$14 million Group One.

The £350,000 (HK$4.14 million) total prize money of the Queen Anne represents little more than a domestic Group Two for Able Friend, who has already won more than HK$44 million and will be chasing six straight wins on Sunday.

Admitting to not being able to match the financial clout of Asia's invitational events, Ascot officials have enticed Able Friend's owner, Dr Cornel Li Fook-kwan, and Moore with a mix of first-class hospitality and the chance to make history.

"The last thing I will do is talk about our prize money on a global level," said Ascot's head of international racing Nick Smith. "For Able Friend, Dr Li and John Moore, it is entirely a goodwill mission as far as I can see."

Smith said Ascot was viewed by many as a way to boost their horse's breeding value postcareer, but Able Friend has no residual value post-career as he is a gelding.

"That's what makes it one of the great sporting gestures we've ever seen in racing. They'll be coming purely to carry Hong Kong's flag on Europe's greatest stage," Smith said.

Earlier this season Li knocked back a chance for an all-expenses paid trip for Able Friend to compete in the Dubai Turf, where the five-year-old would have started a short-priced favourite in the US$6 million event.

While an invite to most of Asia's international Group One races comes with airfares and costs covered for horses and connections, Royal Ascot is believed to have offered a subsidy of around half of the estimated HK$120,000 it will cost just to fly the 1,300-pound horse to England and back.

But what Royal Ascot lacks in stake money and travel allowances though, it more than makes up for in terms of VIP treatment, with what Smith described as "very high-level hospitality" on raceday.

What is also appealing to Able Friend's connections is the chance to categorically prove they have the best miler in the world in the straight feature.

Should he make the trip, Able Friend is likely to face Dubai Turf winner Solow, Japanese-bred Breeders' Cup Mile winner Karakontie and last year's 2,000 Guineas winner Night of Thunder.

"Able Friend is definitely the best miler is Asia, and probably the best miler in the world, but Solow might have something to say about that," Smith said.

"You put them together and you've got Asia's best versus Europe's best in a genuine showdown."
