From humble beginnings, Lady Extreme has developed into a flagship horse for emerging trainer Blake Ryan.

When Lady Extreme initially arrived at Blake Ryan's stable, it was supposed to be a stop-gap visit.

She had been slated for the broodmare barn and Ryan was doing a favour for her owner-breeder Luke Wilkinson by housing her for a few nights until Wilkinson could arrange transport to a stud in Victoria.

Just hours before she was due to get on the float, Ryan received a phone call.

"He was going to retire her and breed from her unraced," Ryan said

"She got to mine on the Friday morning and she was booked to go to Melbourne on the Monday night. Luke rang me at ten o'clock on Monday morning and said, 'do you want to have a crack with that mare? No expectations'."

Both parties are glad Wilkinson made that call.

Lady Extreme has now raced 12 times for five wins and $270,000 in prizemoney, not to mention boosting the stocks of her dam Wanted Lady, who Wilkinson also owns.

She gets another chance to add to her record in the Congratulations James McDonald Handicap at Rosehill on Saturday and Ryan has been unable to fault her condition since her return from Grafton where she finished sixth in the Ramornie Handicap (1200m).

While cautious Lady Extreme has to lump topweight of 60.5kg and extend to 1400m for the first time on a heavy track, he says if she is beaten, it won't be for want of trying.

"It all depends on how the race is run but one thing you know with her is she goes out there and gives 110 per cent every time," Ryan said.

"I think she will run it and we definitely know she appreciates wet tracks but the combination of a big weight at her first time over 1400 on a heavy, what that will lead to is a different question.

"But she seems like she is in good order. She's had a good prep anyway so we'll see what happens on Saturday and whether we pull up stumps and give her a break or press on with her."

Ryan has 35 boxes at Hawkesbury and Lady Extreme, who has won two of her three starts this campaign, has been an important horse for his yard.

In the ever competitive Sydney arena, finding a competitive Saturday grade galloper is critical to success for smaller trainers and Ryan is hoping her performances can open more doors.

"You can get a double on a Thursday and you'll get half a dozen text messages. You get one winner on a Saturday and you get forty," Ryan said.

"I've got one of her, it would be nice to find another three or four.

"I've got about twelve horses up trialling and racing and the rest are young ones coming through so there is always room for more."
