Former Melbourne galloper Truesdale will spearhead trainer Bryan Guy's bid for a winning treble at Doomben on Wednesday.

Guy will saddle up five runners at Doomben, where the false rail will be out 11 metres, and is hoping for a treble to put him within striking range of Rob Heathcote and Liam Birchley who share the Brisbane trainers' premiership lead with 14 wins.

Guy, who won the trainers' premiership two years ago, is currently equal fourth on the ladder with 10 wins.

Truesdale will run in the Weddings @ BRC Handicap (1660m) and is rated by Guy as his best hope along with Lucky Omens in the Xmas Parties @ The Races Handicap (1350m) and Marqualo in the Dec 12 Family Raceday Handicap (1200m).

Cliff Brown, who now trains in Singapore, prepared Truesdale early in his career before he was transferred to Lee Freedman.

"He had a few suspensory problems with Lee Freedman so his owners sent him to me last year," Guy said.

"I gave him two runs and the problems re-occurred so he went straight back to the paddock.

"I thought he was to be retired but I got a call out of the blue one day from one of his part-owners, Ron Wanless, who said he had been in pre-training with Kevin Thomas at Washpool Lodge and was ready to come back into full work.

"Since he's been back with me he's had three starts for two wins and a fourth, all at Caloundra."

Truesdale is a lightly-raced six-year-old son of Zabeel who has won three times during his 11-start career.

Guy believes the gelding is typical of the Zabeel breed and is looking for further ground as he improves with age.

"I think he'll get further later on but whatever happens tomorrow I plan to spell him again," he said.

"Every time I step him up in distance he answers so I'm hoping he'll do it again tomorrow."

Lucky Omens, also owned by Wanless, scored impressively in a 1400-metre class one at Caloundra last month before stepping up in class for a creditable fourth to How Brave in a 1500-metre class four at Eagle Farm on November 3.

"He bolted in at Caloundra but he never quite got the 1500 metres last start," Guy said.

"I scratched him from Ipswich today so he can run tomorrow and from his good barrier (three) he'll run well."

Guy believes the form of stablemate Casholet is a strong pointer as Marqualo bids for the fifth win of his 17-start career.

"Casholet beat Tootsie Zynsky at Eagle Farm last Saturday and Marqualo wasn't far behind Tootsie Zynsky when he ran third to him at the Gold Coast last run," he said.
