Clean Acheeva, the last winner trained by Burles before he retired early in 2018, has been wearing the colours in Victoria.

After she left Tasmania, the mare's Launceston owner Alan Charlton came to a "commercial arrangement" with Burles so the trainer could retain an interest in her career.

He leased Burles' registered black and blue colours.

"Mick loved the horse and it was a really sad call when he told me he simply couldn't handle the dust and cold (associated with training) any more," Charlton said.

"I told him she would wear his colours and in return I would pay him 10 per cent of any prizemoney won.

"Mick did a remarkable job with Clean Acheeva - she performed well in three stakes races against horses from interstate."

Under Burles' care, Clean Acheeva ran third in the 1000 Guineas, fourth in the Strutt Stakes and a close sixth in the Tasmanian Oaks.

Since changing stables and making her Victoria debut last July, the mare has won at Stony Creek and had seven other top-four finishes.

Burles no doubt would have watched her finish fourth at Moonee Valley last Friday night.

"I'll run her one more time in Mick's colours then retire them," Charlton said.

"I've asked (new trainer) Ken Keys to make a special effort to find a race she can win.

"With a bit of help from Mick up above, she might give the colours a fitting farewell."

The fifth race at Mowbray on Wednesday night has been re-named the Remembering Mick Burles Handicap and jockeys will wear black armbands as a mark of respect.

Pacing marvel Destreos achieved two milestones when he won his 101^st race in Hobart on Friday night.

At 15 years of age, he became the oldest Tasmanian winner of the modern era.

And, as a veteran of 465 starts, he is the most-raced horse ever to win in Tasmania.

Harness historian Peter Cooley said that in the 1950s and 60s it wasn't that uncommon for horses to still be winning at 15.

"I can recall a 16-year-old mare winning in Hobart in the early 50s," Cooley said.

"But I can't remember another 15-y-o winning in the past 40 years.

"What I'm more certain about is that there has never been another winner in Tasmania that has had more than 450 starts. And, probably not anywhere in Australia."

Destreos did it in style, leading all the way to score by 11m in 1:57.8. 

Trainer Sally Stingel later won with Rowley to complete her first double.
