Minding heads a formidable challenge by the Aidan O'Brien stable on the Qipco 1000 Guineas at Newmarket on Sunday.
The daughter of Galileo has headed the ante-post market on the back of her two Grade One victories in the Moyglare Stud Stakes at the Curragh and the Fillies' Mile at Newmarket.
While O'Brien expects her to be suited by a step up in trip, he is happy to begin her three-year-old career in the mile Classic.
"You would imagine she'll get a mile and a half - she's a Galileo filly - but she got a mile very easily last year," said the Ballydoyle trainer.
"The best part of her in the Fillies' Mile was in the final half a furlong. You'd imagine she'd get a mile and a half, but we'll obviously start off at a mile."
O'Brien is also represented by Ballydoyle and Alice Springs, and all three have had good preparations, according to Coolmore's UK representative Kevin Buckley.
He said: "It's been very straightforward and all has gone well winter time with Minding.
"Minding does have the advantage of having won here last season over a mile and Ryan [Moore] and we know how complimentary Ryan was when he got off her.
"She is very talented and has done very well over the winter, equally Ballydoyle has, too.
"There is a real high-quality level of Classic fillies this year. They were one, two, three in the Moyglare [Minding, Ballydoyle, Alice Springs] - if that could be replicated on Sunday that would be wonderful.
"Ballydoyle did a very nice piece of work on Saturday and Minding did as well.
"Although on far-from-ideal ground, Alice Springs has had a run and she needed to run.
"I think you will see a much-improved filly on Sunday. She has had eight starts and danced every dance."
Blue Bayou was only fifth in the Moyglare, but her trainer Brian Meehan is convinced that was not her true running.
"We have long thought of her as a Guineas filly and at this point in time she would be one of the best three-year-old fillies that I have ever trained," he said.
"She's already won over seven furlongs so I don't think the mile will be any issue for her and then there are plenty of races for her at that trip.
"When she was beaten in Ireland, Jimmy [Fortune] got off her and said that it was a rough race and that the soft ground had not suited her.
"She had a break shortly after that [Curragh] and did very well over the winter. She came back in on January 1 and has done very well since.
"I took her over to Richard Hannon's on Sunday for a change of scenery and she went up the Polytrack there with her lead horse and she went very well.
"You would obviously have stamina concerns but I think she would be fine up to a mile as she is relaxed and switches off in her races."
Mark Johnston has always had the highest of opinions about Lumiere [pictured above]. The grey has not let him down yet and the Middleham trainer is of no doubt she will last out the trip.
"While some sceptics question her getting one mile, I am not one of them. There is no doubt in my mind that she will stay the trip," Johnston told www.godolphin.com.
"She has so much early speed, I can see why some may doubt her, but I can report she has been very settled in her work at home.
"Lumiere is one of my favourites. She is right up there in my top three two-year-olds of all time, now we shall see if she can graduate to the same bracket as a three-year-old. She is already a Group One winner, and a very exciting filly.
"We also have Fireglow, by Teofilo. She has been working with Buratino and Lumiere and is a very nice filly."
Lumiere's Group One triumph in the Cheveley Park Stakes came at the main expense of Illuminate.
The Richard Hannon-trained filly then went to America where she finished sixth in the Breeders' Cup Juvenile Fillies Turf over a mile.
"I was really pleased with her American run, it was pretty soft ground out there and I thought she stayed on well," said the Marlborough handler.
"She's six months older, she'll be a little bit more mature and when we do run her over a mile we can ride her a bit differently and hopefully the ground will be a bit quicker."
John Gosden's Nell Gwyn winner Nathra adds to the home defence, with Jim Bolger's Turret Rocks and the Criquette Head-Maarek-trained Midweek among the other major contenders.
Jet Setting, winner of the Leopardstown 1,000 Guineas Trial, takes her chance after being supplemented at the confirmation stage by Curragh trainer Adrian Keatley.
Completing the line-up are Aljazzi, Epsom Icon, Mix and Mingle, Robanne and Sharja Queen. The only withdrawal at the 48-hour final declaration stage was the Kevin Ryan-trained Ashadihan.
