Inspiral will enter unknown territory at the Breeders’ Cup as the filly steps up to ten furlongs for the first time in the Filly & Mare Turf.

Trained by John and Thady Gosden, the daughter of Frankel has achieved five Group 1 victories, including back-to-back wins in the Group 1 Prix Jacques le Marois at Deauville. She arguably produced one of her best performances when skipping clear in the Group 1 Sun Chariot Stakes at Newmarket in early October, beating dual French Group 1 heroine Mqse De Sevigne by three-and-three-quarter lengths.

"It's all systems go and the plan and we're all very excited," said Chris Richardson, managing director for Cheveley Park Stud.

"John Gosden seems very happy with her, so at the moment, fingers crossed, if there are no setbacks we're looking forward to next weekend.

"She couldn't have done it more easily at Newmarket (last time) and stamped her authority and John is very happy with where she is, so we may as well roll the dice again.

"The way she finished at Newmarket, she wasn't stopping and she was well clear in the Sun Chariot.

"I think that gave us reason to think the slightly further trip on that sharper track at Santa Anita would suit her perhaps.

"It's unknown territory, but depending on the run of the race, we think she will see it out.

"It will give us a few more options for, all being well, if she stays in training if she does stay a bit further."

Inspiral is the current favourite for the Breeders' Cup Filly & Mare Turf at 5/2, with fellow European fillies Warm Heart and Lumiere Rock near the top of the betting.
