Charlie Appleby has full confidence both Betfred Derby hope Ruling Court and Oaks favourite Desert Flower will cope with the step up in trip when the Newmarket winners tackle a mile and a half at Epsom next month.
The duo impressed on the Rowley Mile when landing their respective Guineas and Appleby feels their class negates any nagging stamina doubts there may be.
"Of course there is an 'if', but we go there with confidence and William (Buick) will ride them with the confidence they will get the trip," said Appleby.
