Glen Boss will ride in-form Queensland mare Pickabee in a track gallop at Caulfield ahead of their assignment in Saturday's Group Two Tristarc Stakes.

Boss will be legged aboard Pickabee on Tuesday morning with Sunshine Coast trainer Caitlin Lavin keen to give the mare a course proper hit-out to familiarise herself with the layout of the track before the Tristarc (1400m).

Pickabee earned the Melbourne trip with an impressive win at Doomben on October 5 when she reeled off brilliant sectional times, including a final 200m split of 11.09sec.

Pickabee was flown to Melbourne in the early hours of last Thursday morning and Lavin said she had settled in well to her new surroundings at Mornington.

"The scariest bit for me was loading her onto the plane because she can be a bit flighty but she was actually perfectly behaved," Lavin said.

"Once I put her on that crate and she was heading towards the plane that was all I could do for her but she travelled really well and arrived safely which was a weight off my mind."

Pickabee will be stabled at trainer Jason Warren's property at Mornington for the duration of her Melbourne campaign.

"We tried to find somewhere very similar to our property up here and Jason was kind enough to let us stay with him," Lavin said.

"His place is basically the same as ours, just on a larger scale, with day yards and a paddock for her.

"There's also a pool which we rely on quite a bit and the beach is only five minutes away."

Lavin said Pickabee was difficult to handle earlier in her career but her manners had improved markedly in the past six months.

"The more we've varied her work the better she's become and I think trust is a big thing with her," she said.

"She trusts what we're doing with her now because, touch wood, there's been no incidents.

"In the past we could barely get her to a race that's how difficult she was but I think she's learning, she's growing up and knows what it is to be a racehorse now."

Lavin believes an interstate trip will also benefit her development.

"Speaking to a lot of trainers they think nine out of 10 times it's basically a working holiday for the horse," she said.

"It freshens them up, everything's new around them and mentally and physically it does them the world of good."
