The horse racing world is mourning the loss of Highfield Princess, a remarkable Group 1 sprinter who has sadly passed away. The seven-year-old mare suffered an “inoperable fracture.”

Despite efforts to help her recover, she tragically lost her fight for life on Saturday evening.

Her trainer, John Quinn, and his son Sean confirmed the sad news on Sunday. Highfield Princess was a true rags-to-riches story in British racing, rising from a low-grade handicapper to win numerous prestigious Group 1 races.

Her victories included the King George Qatar Stakes at Goodwood and the Prix de l’Abbaye at Longchamp, each worth around £170,000.

John Fairley, the owner and breeder of Highfield Princess, said it was “the privilege of our lives” to have raised her. He described her as “the horse you dream of breeding and owning.”

And said he and his family were “heartbroken” by her loss.

In a statement, Quinn Sr. praised Highfield Princess’s exceptional ability and attitude.

“Whether it was a routine canter or a big sprint race around the world she would put in 100% effort into what she did. I am grateful for all that she did for herself and for our team. We will miss her more than words can say.”

Doug Campbell, another trainer, shared his sympathy on X (previously known as Twitter), saying: “Absolutely gutted for you all, she was a star and a total credit to everyone connected with her.”

Tim Easterby, a fellow peer, wrote: “Very sorry to hear this, what a wonderful race mare she was.”

Racing journalist and consultant Andrew Hawkins also responded, saying: “So very sorry Sean, John and everyone who loved and worked with her.”
