Family tradition continues
As a young girl, Gilfillan watched her mother Karen win the open women's 6km event.
Her older sister Ashlea emulated the feet a few years later and younger sister Jessica got her name on the trophy in 2007.
"It was good to come back and run it ... I haven't run it since I was a little girl," she said.
"It was sort of emotional in a way.
"As a family that's where we started. When I was little and saw mum win it and thought I want to win it one day."
The win came a day after Courtney finished third and Jessica second in the Queensland Cross Country championships.
The fun run was also a training run for Courtney as she prepares to represent Australia, alongside Karen, at the World Triathlon Championships in Canada early next month.
"It's a family tradition," she said.
"That was definitely a motivation ... to get my name on the trophy as well and to support a local community event. It was satisfying to know how far I've come since I ran there when I was little."
Courtney's time of 21 minutes 13 seconds saw her finish 43 seconds behind men's winner, Blayne Arnold.
The result was a reverse of Saturday's cross-country where Courtney passed the Gold Coast student two kilometres into the race.
"Me and my sister beat him," she said "He wasn't having a good day I think."
Arnold said it felt good to win after a disappointing result in Brisbane.
"I came out to blow some cobwebs off and put down a solid run and prove to myself I can still run," he said.
And the proof is in his official winning time of 20 minutes 30 seconds.
Paige Single, 16, proved she doesn't need hurdles to excel, winning the open women's 3km race.
Last year, Single made headlines finishing fourth at the Australian track championships in the 15-years girls 3km steeple chase, behind winner Jessica Gilfillan.
"It (flat track running) is much easier, but I like doing steeple chase," she said. "It's an extra challenge and I like jumping in the water as well."
The win was Single's second, after winning the Under-17 girls 5km fun run at Ballina.
Stuart Lorimer won the men's 3km race.
The event attracted 508 runners to the course around Southern Cross University and raised $8000 for the Our Kids charity.
