She dedicated her victory with Ivana Legacy to the memory of her late father, Ron Lilley, who died last month.
Armour hoped her father would have looked down on the horse during last night's race, she said.
Lilley was an integral part of Branxholme trainer Nathan Williamson's stable.
"He worked for Nathan for five or six years and he absolutely loved it out there. It was his dream job," Armour said.
Armour's first training win could be considered a minor accomplishment compared to her others over the winter.
Last month she gave birth to her second child, Beauden.
Armour's husband Andrew - known as Archie- was booked to drive Ivana Legacy the night Beauden was born.
"He was born on the 15th of June. It was the night Archie was meant to go up and drive her, so it was a good thing he didn't.
The couple have a daughter, Brooklynn, who watched her mother's win with Ivana Legacy at home on television.
Armour showed she is as tough as anyone in racing by getting back in the saddle to ride horses in training less than a month after the birth of her child.
"I started a couple of weeks ago because I have a show horse, who is a standardbred, and I am going to take him to the royal show over cup week [in November]."
Notching her first win before her first season of training ended was a big relief, Armour said.
"We have only had four horses in work over the season and when you get seconds and thirds you think the end of the season is coming and we are still on zero."
Some Legacy defied her purchase price when sprinting to win race 2.
A large group of owners paid just $1000 for the horse on a standardbred auction website. She returned more than five times that price to her owners in stake money with her win last night.
Premiership-leading reinsman Blair Orange started last night's Forbury Park meeting with a milestone of his own.
His win with Madaboy in race 1 was his 1600th in New Zealand as a driver.
Orange went to 1601 when winning race 6 behind the Regan Todd-trained Omar Sharif.
Todd also trained Possente Cavallo, driven by Robbie Close, to win the feature pace, race 8.
Close also won a bizarrely run race 4 with the outsider, Shindal, trained by Steve Lock.
The race was run Tour-de-France-style, in two pelotons, before the sprint went on approaching the home straight.
The feature trot was won by Pyramid Magic in the hands of Matthew Williamson.
The win extended the lead of Matthew's father, Phil, in the Otago trainers' premiership to four wins.
Matthew Williamson scored a double when winning race 9 with Magnetic Watch.
