WINTER will test her stamina as she leads a five-strong Ballydoyle squad into battle in Sunday's Group 1 Qatar Prix de l'Arc de Triomphe.

The Coronation Stakes, Nassau Stakes and dual classic heroine is the pick of Ryan Moore but tries a mile and a half for the first time and suffered a surprise defeat, over a mile, in the Matron Stakes at Leopardstown last time out.

"She's been in good form since Leopardstown and everything has gone well," said trainer Aidan O'Brien. "Obviously you can't be sure about the trip as the furthest she has gone was the mile and a quarter at Goodwood."

O'Brien's dual classic winner Capri has been dismissed by punters at around 20/1.

"He's in good form. Obviously he hasn't done a lot since Doncaster, but he seems to be in good form," said the master of Ballydoyle.

Order Of St George, third last year, would be suited by rain, with O'Brien adding: "He's in good form. We've been happy with him since the Irish Leger at the Curragh and everything has gone well."

Idaho and Seventh Heaven complete the team.

FAVOURITE

Having carried all before her this season, John Gosden's Enable aims to finish it with a flourish at Chantilly. The Oaks, Irish Oaks and Yorkshire Oaks are already in the bag, as well as victory against the boys in the King George VI And Queen Elizabeth Stakes at Ascot

With a field of 18 going to post, Enable fared well in the draw, pulling stall two, but Gosden is not counting any chickens and would have preferred Frankie Dettori's mount to have been in the middle.

"It was always going to be a big field, which is the reason we didn't want to run Cracksman in it. It is good opposition and it is a proper Arc," said Gosden.

"Horses with a high draw have the initial advantage, as it is a bit like in the boat race and the jockey will have to work out what to do. Luckily he has to make that decision, not the trainer.

"I always think the middle draw is best, but we are where we are and we've got to get on with it. I just hope we don't get too much rain on the day. I would love to see it on better ground, when you see the good horses quicken.

"The filly is well in herself. She is a lovely filly and she is well. She is weighing more now than she did at the beginning of the year, which is a good sign.

"I think there are five or six really nice other horses in there, not one to be afraid of. Remember, Chantilly is not an easy track, with sharp bends. Not always the best horse wins."
