Winx breaks the mould of what a horse can and should be, and champion trainer Chris Waller believes she might, as a seven-year-old, be going better than ever.

She has already done things Waller didn’t think he would see in a horse and it wouldn't surprise him if she continued in that vein in the spring.

She lines up for a fifth spring campaign; the past three have delivered a Cox Plate at the end of them, and that's the target again. There is another record ready to broken in the race which now carries her name, the Winx Stakes, at Randwick on Saturday.

She is looking for a 26th consecutive win to surpass the winning streak of another great mare, Black Caviar.
