If anything, her background encapsulates the spirit of the games.
Andrew Bachelor, a friend of her husband, Phil, is a Rotorua sprinter who got the ball rolling during a visit here in November and within three days Beamish-White had paid her entry fee of $350 as act of commitment.
"Knowing if I hadn't owned up and committed myself, you know, it would have probably just passed."
The mother of Connor, 10, Charlotte, 8, and Daniel, 7, used to be an athlete at Waiuku College, representing the school to district level.
"I wasn't like the best. I was probably middle of the road once they got to the regional athletics," she says, revealing she was good in several disciplines but a specialist in none.
Phil Beamish-White hints of scepticism turned to a pillar of strength for his wife when he realised she was serious. He scanned and selected YouTube footage for her to hone her skills.
"A big thanks to him because nothing was done while I tried to be a professional athlete.
"Every night and every day I did everything to get to that point," he says of the operational manager at a lumber mill.
He also printed T-shirts of support for the children and her parents to wear at the games.
"I don't think my husband thought I was serious or whether I was capable, I'm not sure," she says with a grin. "He wasn't too enthusiastic because, you know, I was pretty unfit."
That is not to say Beamish-White was inactive leading into the games. She has been a regular at lawn tennis for a few years.
She isn't trying to make out that she is a fabulous athlete or anything post-games but, quietly, she was always mindful she was capable.
"You've got to remember that other people who were really good aren't doing it now so there's a bit of luck there, too," she says, throwing her arms up in the air in a smile to acknowledge that when she was at school everyone was doing it so she was just one of many.
Conversely Beamish-White feels having some former pedigree athletes at the games is good for those like her to strive to keep up with them, if not beat them but "there were no donkeys there".
Needing to lose some weight as well, Beamish-White enrolled at a boot camp in her neighbourhood with uphill interval training before zeroing in on the specifics of athletics only a month out from the games.
That entailed borrowing high jump equipment from her children's primary school as well as surfing Trade Me for a pair of second-hand spikes, a shot put and javelin.
With the kapa haka gathering at the HB Regional Sports Park at the time, Beamish-White had to train at the Hastings Girls' High School grass track.
"That was quite hard work and I was sprinting in shoes that I'd never done before so I was feeling a little demoralised after that," she says with a laugh.
As she got fitter she joined the Hastings Athletics Club to make the most of the all-weather track to jog her muscle memory, especially in hurdles.
"After the kapa haka, it went back to the athletics track and, I think, there were like two meets before the season finished."
At the penultimate outing her paths crossed with fellow games athlete Pam Minor, of Napier, and she found a buddy to train with.
"We were both novices," says Beamish-White, pointing out the scars of shot put attempts in her backyard, not far from a high jump landing pad facing the kitchen window.
She didn't find much love with the high jump bar so she abandoned that part of training but had to do it as part of the seven-discipline heptathlon.
Son Connor joined Beamish-White to race around the house in 100m sprints. He was much faster but that played into her hands in incrementally shaving off valuable fractions of a second when she started to plateau.
Her parents, Jenny and Michael Clarke of Napier, often came along to time her runs and measure her throws and jumps.
Her training buddy's contribution was godsend for someone who, owing to a rural school, found the use of starting blocks a foreign concept.
"I found at Mt Smart everyone was using starting blocks and I'm just standing there," she says of Minor's help.
When her children were attending tennis lessons some of the other mothers often helped her during her javelin throws.
"I didn't really know what I was using and with Pam we helped each other and I knew where we had to be because you can look on line at the records," she says of Minor who won gold in high jump and silver in the heptathlon (45-49 grade).
That came as an endorsement that Beamish-White wasn't too bad apart from the 100m sprint because "you can't time yourself".
The North Island Championship results spurred her on. Hastings club members Dennis O'Leary, Alan Dougall and Willie Stephenson were brilliant in helping overcome the mental block in clearing hurdles.
"I've always been a nervous type of person," she says, disclosing how when she took her mark in the 100m heat her leg shook so much that she lost her balance on the starting block to finish runner-up.
On reflection she spent more time on a physiotherapist's table than out training, owing to a niggly injury she picked up on her calf in February but it miraculously came right a week before crunch time.
The stars also aligned with the moon, as a friend in Auckland lent her home to the Beamish-Whites for use for 10 days while she was away travelling.
"It was really neat to hear them cheering for me. My parents as well. My mum's always been my big cheerleader anyway."
The long jump left an indelible impression on Beamish-White.
"I had a really good day and I was hitting the board so every jump was a really good jump for me," she says, feeding off the crowd's clapping and cheering.
Beamish-White's acknowledgement extends to the "awesome athletes" whose reciprocal appreciation made it possible for everyone to aspire to be the best one wished to be.
"I was just learning and trying to improve but there were some people from Peru, Italy and Canada so it was a really close group."
Needless to say, Beamish-White has caught the need-for-speed bug.
