The four-year-old has won three races since resuming from a long spell but her last-start failure in the Golden Mile at Spreyton has left trainer John Blacker in two minds.

"She continues to work really well so I think we can forgive her one bad run," Blacker said.

"Her previous form was very good and she should run 1800m around Longford.

"But, if she runs poorly again, she'll go to the paddock."

If she performs well, Triple Strip will go on to next week's $100,000 Devonport Cup at Spreyton where she has a good record.

The Needs Further mare is one of three runners for Blacker in his home-town cup that he has won previously with Raami's Magic (1996) and The Producer (2014).

"I've finished third for the past two years with the favourites Beaufort Lad and Zatacla and this year's race doesn't look any easier," the trainer said.

"But my three runners have all got a chance.

"Settler's Stone is not well weighted and has to be ridden back in the field but he's as good as gold and will be finishing off strongly.

"Magnasa is super fit and getting out to a suitable distance so, with barrier 1 and Craig Newitt, I can see him running well."

Blacker said the annual Longford meeting was important to his stable being on his home track and he would be represented by a strong team.

"I've got good chances in most of the races, with Mag Wheels (race 5) probably my best," he said.

Mag Wheels will also be ridden by Newitt who won three races at the meeting in 2018 and four last year.

Standing-start specialist Full Speed Ahead will return to his favourite part of Tasmania for Wednesday's $12,000 St Marys Cup.

Two years ago, the gelding completed the North East feature double when he dead-heated for first in the St Marys Cup then won the Scottsdale Cup.

A lot of water has passed under the bridge since then, including a period when he managed only one minor placing in 15 starts.

But he has regained form since joining Pipers River trainer Marc Butler and will be one of the favourites for this year's race despite his 20m handicap.

Normally a very good beginner, Full Speed Ahead has recorded nine of his 15 career wins in standing starts and driver Ricky Duggan will be looking to make up some of his handicap in the early stages.

Two starts ago, the nine-year-old was runner-up to Ryley Major in track record time in a heat of the Golden Apple. He led again in the final before wilting slightly to finish sixth, a result Butler put down to the eight-day back-up.

With a slightly longer gap between races this time and having been given an easy time on the training track, a return to his best form is on the cards.

There is no off-course betting on the non-TAB meeting but several bookmakers will be on course.

Bush fires in the Fingal area pose no threat to St Marys but patrons have been advised they may have to find an alternative route to the track.
