John and Thady Gosden's Inspiral will take on some of the best fillies from the UK, Ireland, France and the USA in the Coronation Stakes at Royal Ascot on Friday, June 17.
Frankel filly looks every inch the star after starting her career with four wins in a row, culminating in a bet365 Fillies' Mile success last October.
Yet there may be value elsewhere in the field given the three-year-old hasn't run since then and was swerved away from the 1000 Guineas at Newmaket.
Her opponents including Cachet and Mangoustine have both run this season with the pair fighting it out in the French 1000 Guineas at ParisLongchamp in May.
Chris Richardson, representing owners Cheveley Park is aware of the challenge at Ascot for Inspiral: "We've obviously been very patient, but she seems in good form. John Gosden and Frankie Dettori were happy when I saw her last week, so at this point in time we're green for go.
"It is a tough race and it is first time out, but it's the logical race for her and where we have to go, so we'll all hope we see something.
"It will be exciting to see her back in action, for sure."
John Gosden is hoping the softly softly approach will pay dividends.
He said: "It has taken a long time, but I think we are beginning to see the filly of last year. Hopefully she can put in a big performance."
Meanwhile, Cachet, trained by George Boughey has been brilliant for Highclere Thoroughbred Racing, taking the Newmarket 1000 Guineas and Harry Herbert from the syndicate organisation said: "I saw Cachet last week and she looks absolutely fantastic. She really looks like she is getting stronger all the time.
"George is very pleased with her work and James (Doyle) sat on her and did a piece of work and likewise, he was chuffed to bits with her, so fingers crossed.
"The faster the ground - we know she loves that. It is very much up her street. We are really excited. It is such a thrill to have done what she has done and heading into a Coronation touching wood, from what we are seeing at home, in as good or better form than she was."
French raider Mangoustine is used to the rain spattered ground of Northern Ground but trainer Mikel Delzangles exepects the turf to be well managed by the Ascot grounds staff.
He said: "She looks in great form and she is drawn in stall one, which is better than 12 I would say.
"I think she will be all right on the ground. They will water to make sure it is safe, I'm sure, and as long as it's safe we're happy.
"It is a hot race, but we would not expect to have an easy race in Ascot - that's competition.
"She's in great form and ready to do her best."
