It sounds like the Derby winner has come through the race really well.

"After trotting her up I took her for a pick on the lead. She put her head down to graze for a while and then decided to have a roll then a squeal when she leapt to her feet."
"This morning I decided to give her a light trot and canter under saddle just to be doubly certain. Everything about her tells me she is a very happy horse."
