What does might have got to do with it though? Zarkava didn't stay in training, and Goldikova has since progressed past her, hence has proven herself to be the better horse, not to forget the more durable, and has won in England and America.
Exactly, when Zarkava was beating Goldikova, Goldikova was struggling to beat the likes of Halfwaytoheaven (admirable filly that she was).
To me Goldikova has always got better as the season progresses and this year looks to be no different.
Someone else was right to mention, if this was O'Brien, Fabre or Stoute training her we should be hearing how great a training performance it was by them to keep her sweet and on the go. Great achievement by Head.
