Katherine Coleman excited to officially enter partnership with Peter Moody

Katherine Coleman's first starter in the new training partnership with Peter Moody could be delayed 24-hours with a Pakenham entrant poorly drawn on Tuesday.

The Moody-Coleman combination will officially launch from August 1, the culmination of a three-year plan between the master and apprentice.

Moody, a 57-time Group 1 winner, returned to racing in the 2019/20 season after a five-year hiatus with Coleman an assistant trainer.

"I can't say how thankful I am and how grateful I am for the opportunity," Coleman said.

"What a big step it is for me and to be a part of stable, with the quality of horses we have, is unbelievable for someone starting out.

"We were just talking the other day about the first day we filled the stable up with horses, it feels like yesterday not three years ago."

Runsir, a five-year-old gelding set to resume in an 1100m maiden at Pakenham on Tuesday, could be the Moody-Coleman yard's first starter should they elect to run from barrier 11.

Scorsese, a two-year-old colt entered in a 1210m maiden at Sale on Wednesday, would be the fallback option should Runsir be scratched.

"Possibly Tuesday, or Wednesday, so we can kick off with a winner," Coleman laughed.

"He's (Scorsese) tightened up nicely, they were just a little bit sharp for him the other day, so we'll stretch him out in trip now and hopefully get that maiden out of the road."

Coleman's inevitable promotion to co-trainer has gathered momentum the past 12-18 months.

"It was the plan right from the start ... he (Moody) wanted to train in his own name for a few years, get the ball rolling again and make sure he and I worked well together.

"It was always the plan, eventually, to happen, nice it's finally come to fruition."

The addition of Coleman has enhanced the dynamic between Moody, racing manager Jeff O'Connor and jockey Luke Nolen, the collective brain trusts behind the Pakenham operation.

Modest Coleman, a gun operator with a natural feel for horses, said the only change from August 1 would be her name being printed in the racebooks.

"It will literally just be the name change," Coleman said.

"Obviously he's the senior trainer and we work together now anyway and bounce ideas off each other all the time.

"I'm just lucky to have him as a mentor there, guiding me along."

Coleman's parents, Rob and Heather, will travel from Perth to be trackside at Flemington on Saturday for the new-look stable's first metropolitan meeting.

Dance To Dubai, a last-start Flemington straight winner, will tackle the Group 3 Aurie's Star Handicap (1200m).

"She was so good there last start, so it's an obvious options for her," Coleman said.

"She's come on well from that run, too."

Affable Coleman laughed when asked about any past disagreements with Moody on the preparation of horses.

"A couple of little ones," Coleman said.

"I've got to make him think it was actually his idea, so it's like mind games!"
