The Nick Olive-trained Fullerton will be shooting for back-to-back victories over the 2000-metre trip on Sunday when he lines up in the feature race at Thoroughbred Park.

The reliable five-year-old, which took out the feature event at the last Canberra meeting, tackles Sunday's Canberra Hummer Benchmark 75 Handicap.

The race could mark the end of a consistent campaign for Fullerton which, Olive said, will most likely be sent to the paddock.

From 12 starts this time in the Fastnet Rock gelding has scored three wins and six seconds. "He's only been out of the placings once, so it's been a really good campaign for him," Olive said.

Experienced rider Jeff Penza, who was in the saddle for their last-start win, retains the mount on Sunday.

Olive is confident Fullerton will perform strongly again and is expecting a forward showing from the inside alley.

"I thought it was one of his best wins of his career last start, and I expect him to go well again," the Canberra trainer said.

"He'll obviously be in a fairly forward position, but Jeff knows the horse pretty well, so I'll just leave it up to him."

Olive believes veteran galloper Sebony will pose the biggest threat to Fullerton following his win in the Cooma Cup over 1600-metres last start.

Sebony will start beside Fullerton in the barriers, but having not raced over a trip longer than 1750-metres in his 61-race career the distance is a big query for the nine-year-old.

In fact, Sebony is yet to win beyond 1600-metres, but he does have a very strong record on the course proper at Thoroughbred Park.

Fullerton is yet to race over a trip longer than Sunday's feature race, but Olive said that was likely to change when he resumes racing next year.

"Next campaign I would like to try and get him over 2000 [metres] for sure," he said.

"It's pretty hard to find anything over 2000-metres, so whatever comes up we'll try and put him in."
