Winx went to the Turnbull Stakes before the Cox Plate last year, and it is the favoured path once again.
Her winning run, which stretches over three years and across 26 races, has had its home at Randwick. She has 15 wins there, and the 1600m has been her best trip.
Winx has won eight races from the mile start near Alison Road – seven at the top level, including an Epsom, a Doncaster and the past two George Main Stakes, where she beat the subsequent Epsom winner on both occasions.
“She is just constantly in the zone and everything is going to plan. The jump-out last week was perfect. It was just enough to keep on top of her with the four weeks between runs,” Waller said. “She will love stepping up to the mile.”
Waller has always said he will retire Winx when she shows signs that she has had enough. But while she continues to win, there is no reason to end her career.
