Until September last year, she was serving as a lance corporal in the New Zealand Army's engineer corps.
"I joined the army because it sounded like a pretty sweet opportunity.
"I love hands-on jobs and being outdoors, and it was also a cool way to get some experience and travel," Goomes told the Rotorua Daily Post.
She saw those same opportunities in the career of a professional mountain biker.

For the Chatham Islands native, it was a choice between two dreams.
"I realised it's hard to be a good soldier and a professional athlete at the same time.
"I was doing okay at both. But I wanted to go farther."
In 2020, Goomes decided to make the jump.
After five years in the army, she moved to Rotorua to give professional mountain biking her all.
At the recent Giant 2W Gravity Enduro, Goomes' determination paid off.
The event, regarded as the largest of its kind in the world, saw 600 riders race from the hub at Te Pūtake o Tawa for prizes, pride, and fun.
At the podium, the Dunlop family handed Goomes her award.

"At the moment the big dream is to get to the Red Bull Formation in Utah.
"I think I can make that happen."
Already, she has plans to race in Austria, Italy, and France later this year.
They will be Goomes' first overseas races.
Asked about how she powers through her training, Goomes laughed.
"Pain is progression," she said.
Goomes doesn't talk about nerves. For her, it's more about having a thrilling time.
"Riding is super fun. Racing is fun. When you get a good result it just shows you're doing the right things."

"To be good at either one you need to be motivated, motivated to work hard and focus."
Rotorua Mountain Bike Club president Clair Coker described Goomes as someone "to look up to."
"She's fantastic. She's so inspiring and humble and super kind, and she wants to have fun.
"She's working really hard and she knows you've got to get out there and make opportunities for yourself."
Goomes said "it's cool" to stretch the boundaries of what is possible.
"Hopefully I can pave the way for more girls to do mountain biking professionally.
"If they can look at me and think, 'She's doing this.' Then hopefully they will feel like they can too."
