It was Winx’s 23rd Group One victory and 31st consecutive win since May 2015, although she was forced to work hard to overhaul chief rival Happy Clapper, who had set the early pace and at one stage led by six lengths.
Winx won for the fourth straight time in the Chipping Norton Stakes.
The Hugh Bowman-ridden Winx won by more than a length from Happy Clapper. The previous record for Group One wins was held by retired Irish horse Hurricane Fly.
“The pace was very solid throughout, as you could all see, and we had to make our own way into the race,” Bowman said. “But she is an amazing horse.”
