The Sir Michael Stoute-trained four-year-old has won three of her six starts at distances of up to two miles – including a brace of victories at Ascot, where she is expected to handle the extra four furlongs of the Gold Cup at 3.45pm.

Estimate secured the first Ascot success in the Group 3 Queen’s Vase at this meeting last year for jockey Ryan Moore, who also rode her to victory in a Group 3 here on May 1 – her sole start of the season.

“She is bred to run over this distance and most flat horses aren’t bred to do what they are doing over this trip anyway,” said John Warren, the Queen’s racing manager, after her last win.

“Through her male line and female line it is true stamina on both sides. If anything is bred to do it, she is amongst them.

“Whatever runs in an Ascot Gold Cup will inevitably be freakish horses as they are not bred to do it, so she has got every chance of staying further.”

Earlier, the Group 2 Ribblesdale Stakes at 3.05pm can go to The Lark, who finished third in the Investec Oaks and can secure a big prize today. In other races, Society Rock is fancied for the Group 1 Diamond Jubilee Stakes on Saturday.
