Gold Coast trainer Kelly Purdy is in a unique position to evaluate temperamental mare Warrior Girl.

Purdy rode Warrior Girl to victory in the 2010m Magic Millions Sprint (1000m) at the Gold Coast and as a trainer has saddled the mare for another three wins.

"It's definitely more stressful training her than it was riding her because she's got a mind of her own and is a real problem child," Purdy said.

"I've tried every trick in the book with her. She really is a trainer's nightmare but she does go well so you put up with it."

Purdy could write a book detailing the ploys she has used to coax the best out of Warrior Girl.

"It's all about doing something different each time to try and out-think her," she said.

Warrior Girl is in her last campaign of racing before she is sold at the Magic Millions broodmare sale in June.

"On one hand it'll be a relief because she's a headache to train but it'll also be the end of an era because she's been pretty good to me," she said.

The six-year-old mare has drawn barrier one in Saturday's Inghams Handicap (1110m) at Doomben but Purdy is concerned by an apparent lack of speed in the race.

"She needs strong pace on otherwise she'll bolt mid-race then stop so I'm hoping she can be smothered up from gate one and go to sleep in the run," she said.

"I've never known a horse that can run sectionals like she can at the finish but unfortunately no-one's ever seen it, her head's always got in the way."

When Purdy retired from riding because she was tired of the "same-old, same-old" she wanted to become a horse acupuncturist before being persuaded to take up training.

"Ideally I'd like to have a dual licence which would allow me to ride and train but they only have that in New Zealand," she said.

"But I've got nice clients to train for and with a team of 10 horses it allows me to ride them in all their work which I still enjoy."
