Kelly Brazier ran and ran and ran, until her lungs were bursting and her legs were screaming in pain and she could run no more.
And then she flopped over the tryline.
Brazier's 80-metre extra-time stunner has seen the Black Ferns Sevens take out Commonwealth Games gold, defeating Australia 17-12 in a colossal decider.
Finishing regular time at 12-12, both sides had extra-time opportunities but failed to take advantage until Brazier collected the ball near her own 22-metre line, jinked past her defender and galloped home.
Coming after the half-time siren for the first extra-time period, the 28-year-old Brazier's effort surprised everyone - not least herself.
"I'm probably not the quickest but I pride myself on a bit of fitness so obviously, 19 minutes in, I had a look around and was like, it's now or nothing - just went for it and had a few chasing but thought, ah, I'm gonna go," Brazier said.
"All I could feel was my lungs going up and down, so I was just worried about trying to catch my breath back, and then the girls jumped on top of me."
Without doubt, Australia will rue a host of missed opportunities.
Pegging back New Zealand's 12-0 lead after Portia Woodman and Michaela Blyde tries, the Australians had a chance to win after speedster Ellia Green's late effort but Emma Sykes couldn't nail the conversion.
Each side was nervous in extra time, with the Aussies coming closest when Kiwi Niall Williams pulled off a miracle tackle to haul in Dom du Toit.
Then, with everything on the line, Brazier collected the ball in an innocuous position, saw no passing options and pinned her ears back.
"Paid off in the end," the Otago-born midfielder said.
"It probably wasn't (clear I'd made it) until I was actually over the line and I was dead. They tried to pull me up but I was just a bit of a dead weight."
As a result, New Zealand becomes the first ever women's rugby sevens champions at the Commonwealth Games, after disappointments in the 2016 Rio Olympics final and recent World Sevens Series events.
It also comes after the mumps-enforced absence of stalwart Ruby Tui.
The Ferns had earlier defeated England 26-5 in their semi-final, with the latter taking bronze after a 24-19 win over Canada.
Brazier was chuffed to secure her own slice of history.
"Rio, it was massive, I've probably seen it in the girls in the past year's performances. It wasn't a nice feeling so we came here wanting to go one better, and we did that," Brazier said.
"We've had a hell of a two weeks, things happening, so extra time was nothing for us given the things we've had to overcome."
