‘She just wasn’t up to it’ – $10 million Winx filly’s career over before it begins

Quinceanera, the record-breaking $10 million daughter of champion mare Winx, has been retired without making a racetrack appearance.

In the end it was an easy decision for owner Debbie Kepitis and her family to cut short the Pierro filly’s racing prospects before they’d even begun, with the rising four-year-old to join Woppitt Bloodstock’s broodmare band ahead of the 2026 breeding season.

Kepitis revealed that Quinceanera had suffered setbacks during her early education before joining the stable of Chris Waller, the trainer of the filly’s champion mother, and they had counted against her getting to the races.

“It’s regrettable, we wish we hadn’t had to make that decision, but she just wasn’t up to it,” Kepitis told The Straight on Wednesday. 

“When she was being broken in, she jumped around in the paddock and hurt herself, and that was why she took so long to get into Chris’s system.  

“We couldn’t have her not perform at her best.”

Kepitis paid a southern hemisphere record price at the 2024 Inglis Easter Yearling Sale to buy out the filly’s co-breeders Peter and Patty Tighe and Elizabeth and Rick Treweeke.

If Quinceanera, whose mother won 33 consecutive races including four Cox Plates and 25 Group 1s during her remarkable career, was able to leave her own imprint on the racecourse it would have been a bonus in Kepitis’ eyes.

“She was always a long-term prospect. From the moment she was born, we had fallen in love with her. It took a lot to decide to buy her. It took a lot of money to buy her,” the well-known owner and breeder said.

“History says that generally really good race mares don’t produce fabulous racehorses … so you always have that in your mind that there’s a chance that they won’t live up to your expectations. 

“We really would have loved to have taken her to the races, but you just don’t want anything happening to her that would be detrimental to racing, if nothing else.”

It’s the second tough decision Kepitis has had to make in the space of about six weeks, with Winx’s second live foal, a colt by Snitzel, withdrawn from this year’s Inglis Easter sale due to an injury.

It is not expected to have a long-term impact on the colt’s racing prospects, but it does leave his breeders in a quandary as to how to sell the late November-born foal.

“He just had a hiccup in his prep and you wouldn’t have taken any horse that was a little bit suspect to the sale,” Kepitis said.

“You want them to be at their best and he needs a few months off and then he’ll be right again. We’re just getting back to being perfect and we’ll see what timeframe that is and make that decision then.”

That crucial decision will be made in concert with the Tighes and Treweekes. 

“That’s a group ownership decision. It’s not mine,” she said. 

“Ultimately, we’re not a racing group anymore. But that’s a decision for down the track. It’s speculation and I don’t like speculation.”

While the Kepitises, the Tighes and Treweekes no longer race horses in partnership, they remain strongly connected through Winx, a mare whose story and racecourse exploits have transcended the sport and become the subject of documentaries. 

Winx is in foal on a September 27 cover to Darley shuttler Too Darn Hot, with her owners keenly awaiting the breeding season for what is hoped will be the safe arrival of her third foal.

A rising 15-year-old, Winx has endured a difficult career at stud, with her first foal by I Am Invincible born dead before producing a foal every second year since.

“She’s looking fabulous and she actually glows when she’s in foal. She’s as happy as she’s ever been and we’re really looking forward to seeing whether we get a filly or colt out of her,” Kepitis said.

Last year’s earlier serving date leaves the door open for Winx to be covered again this year, but Kepitis was non-committal about such a scenario.

“I think personally, if I had my two cents, I’d give her a year off. But there’s a whole group of us and we all have to sit down and chat about that,” she said. 

“There’s no right or wrong to that decision. She would only ever go back if she was healthy and happy. There’s a lot to play out before we even have to make that decision.”

As for Quinceanera’s maiden mating, there are an array of options open to the Kepitises who are shareholders in the Coolmore colts syndicate, a portfolio that includes Home Affairs, Shinzo and Switzerland.

“But you’ve also got a lot of other fabulous sires (to choose from) and Coolmore’s now bringing Delacroix down as well,” Kepitis said.

The Eclipse and Irish Champion Stakes winner Delacroix is a son of champion European stallion Dubawi, the sire of Too Darn Hot.
