Aidan O'Brien has admitted that the hugely talented but equally fragile Rip Van Winkle has enjoyed a far from ideal build up to this year’s Breeders’ Cup Classic.

The dual-Group 1 winning colt has had his fair share of foot problems this season but has still managed to land the Sussex Stakes and QEII and he will be out to win the Classic for the first time for his trainer.

"The horses arrived on Sunday. They'll go on the track tomorrow and have a trot and a canter," O'Brien said.

"Rip has been swimming against the tide all season and it is amazing where he is given the hiccups he has had.

"He's had bits and pieces of problems coming into this race, with one of his feet that hasn't been problematic thus far (this season).

"I hope it isn't going to affect him and we will see him out on the track tomorrow.

"With Rip you have to take it day by day all the time but we have been happy with him throughout the last week.

"I don't think the surface will be a problem as he is a fluent and easy mover.

"He is total athlete and we will see out he handles it when he goes out for a hack tomorrow."

Also representing O'Brien's team will be the Irish 2000 Guineas and St James’ Palace Stakes winner Mastercraftsman who will line up in the Dirt Mile at the weekend.

O'Brien said: "Mastercraftsman definitely runs in the Dirt Mile.

"For us the best performance he has ever put in was over six furlongs on fast ground at the Curragh (last year in the Phoenix Stakes).

"There was a Coventry winner (Art Connoisseur) in that race and he blew him out of it.

"We feel that what was important that day was the pace of the race and he must have pace in a race as he has so much speed."
