Superstar mare Winx has completed a Cox Plate hat-trick, taking out the $3 million feature in a new track record time (2:02.94).

The world's best turf horse was pushed to her limits, with the Weir-trained Humidor looming ominously halfway down the straight.

Hugh Bowman had to lift the champion mare late to salute by just under half-a-length, with Humidor running the race of his life to finish well clear of Folkswood in third.

"Obviously she was in for the fight, it wasn’t an easy victory but you don’t come to these races expecting to win, believe it or not," Waller said.

"She had to be good to fight off Humidor and other runners in the race, it was a fair dinkum Cox Plate."

Bowman said it had been a big build up to the third Cox Plate. 

“I can’t explain, it’s been such a build up. Greg Childs said after we won last year that nothing will prepare you for next year and he was right." 

"She’s made history. I was born the year Kingston Town won his first Cox Plate and to think she’s emulate the great… trying to compare one horse to another, they’re all different animals at the end of the day.

"But we are in the presence of greatness. She’ll be recognised as one of the greatest horses to grace the Australian turf."

Humidor's jockey Blake Shinn said for a moment he thought they could get passed the mighty mare. 

"For a fleeting minute I thought we were going to beat her, but she's just a champion, she just pulls out all stops," Shinn said. 

"It's great to see her win, but full credit to my horse and Darren Weir and his team."

The victory, Winx's 22nd win in a row and 15th Group One, took her career earnings beyond $15.5 million, making her the highest earner in Australian horse racing history. 

Winx joins the legendary Kingston Town (1980, 1981, 1982) as the only horses to win three Cox Plates.
