Former Australian galloper So You Think will attempt to race into the history books when he lines up in the Group One Prince of Wales Stakes at Royal Ascot in the early hours of Thursday morning Australian time.

The Aidan O’Brien trained So You Think is currently an odds on favourite for the Prince of Wales Stakes, despite the fact that the field contains some of Europe’s best middle distance horses.

A win would take So You Think’s UK record to three from three, including two Group Ones. What’s more if he wins with the same amount of authority as he did in the Tattersall’s Gold Cup, he is likely to be crowned the world’s best middle distance horse. So You Think’s timeform rating is currently equal to that of Goldikova and Workforce. A strong win would see him move ahead of both horses.

So You Think’s careers record now stands at 14 runs for 10 wins and three minor placing’s, and one man hoping he will make it win number 11 is former jockey Steven Arnold who said he was looking forward to see how his former mount fared against Europe’s top middle distance horses.

“It can be hard for us to line up how good they are when they’re just racing in our own country, and I could be a bit biased because I was close to him, but I’ll be really interested to see how he shapes up in the better races,” said Arnold who is in England to ride Danny O’Brien’s Star Witness.

“He’s the best horse I’ve ridden. In one way it’s  a shame to lose him, but in another it’s good for racing because he’s a special horse and it would be great if he could go on to  a race like the Arc.”

In a mark of how highly So You Think is rated, English bookmakers have declared him a $1.45 favourite in a race where five of his six opponents are Group One winners.

Planteur was third past the post in last year’s Arc de Triomphe, but was later disqualified for causing interference. Dual Champion Stakes winner Twice Over is also well credentialed but his recent form suggests he will need a lift to overcome So You Think.

The Prince of Wales Stakes is over 2000m, and Arnold is convinced So You Think can stretch out to further, despite the fact that his only defeat in his last ten starts came when he was raced beyond 2000m for the first time in last year’s Melbourne Cup.

“I think it probably took its toll on him a little bit that he won the Cox and the Mackinnon seven days later and had only three days before the Melbourne Cup. He was a really late foal too, so he’s still quite a young horse,” Arnold said.

“When he won his first Cox Plate he was technically a two year old and I wouldn’t be surprised if he can improve on what he did here.”

So You Think will be ridden by top English jockey Ryan Moore in the Prince of Wales of Stakes, which jumps at 12.45am (AEST) on Thursday morning.
