Black Heart Bart will spend the remainder of his days at a Western Australian cattle farm, after connections decided not to send him to Living Legends.

The rising 10-year-old ran his last race at Belmont on Saturday, with trainer Lindsey Smith confirming he had officially been retired.

The six-time Group 1 winner finished his career having won 17 of 62 races with prizemoney of $4,818,580, after being purchased for just $20k in an online sale.

Living Legends confirmed they would be keen to offer a home to the popular galloper, but his connections have decided to keep him closer to them in his original state.

Managing owner Kim Renner, who is a Geraldton builder, said while they were thankful Living Legends had shown interest in Black Heart Bart, they were keeping 'their mate' somewhere they would be able to regularly go and visit him.

"He means so much to us and he's certainly our friend so I've decided to send him to live with a good friend of mine who has a 300-acre cattle farm in Albany," Renner said.

"He'll really enjoy it there among other horses too and it means I can still go and see him more often, there's even a chance that mate's daughter might ride him in shows too.

"I've owned more than 300 horses but he's right up the top of the most special.

"We bought him as a group of five mates and sadly two of those friends have since passed away from cancer and a heart attack, so he's even more special that we were able to share all those moments with him together."
