Talented galloper Mihaul was euthanised on Monday after sustaining multiple knee fractures on Saturday.

The Moira and Kieran Murdoch-trained five-year-old went amiss over the concluding stages of the Hastings - Heart Of Hawke's Bay (1200m) won by Te Akau Shark, and despite efforts to repair the fractures in his left foreleg the gelding could not be saved.

The hitherto unbeaten galloper won his first five starts, the first two for New Plymouth trainer Allan Sharrock.

The Kathy Stanley-owned gelding later joined the Murdoch stable after more than 18 months on the sidelines and looked to be fulfilling his potential with three comfortable victories earlier this year.

“His knee fracture was extensive and would have been very difficult to repair enough for him to have a good quality life,” Moira Murdoch said.

“He is very sadly missed by all who knew him and will be buried at Woburn Farm where he will be always honoured as a super racehorse who loved his racing.

“He was a very good horse and would have been up to the best at 1400m. Sadly he never got that chance, so we will never know, but he had everything – power, speed and temperament – and he loved to run.”
