To further illustrate her achievement, in silver was fellow Kiwi Phillipa Gray, the London 2012 Paralympic champion, riding with pilot Kylie Young.
With the opening ceremony of the Rio 2016 Paralympics just two years away come September 7, there is little doubt Foy could be one of the stars of the New Zealand team in Brazil.
Passionate about sport for long as she can recall, the Northlander played rugby, soccer and netball as a schoolgirl but found her vision restricted her from progressing at team sports.
On completing her psychology degree at Auckland University she took up a role as a gym instructor, and when her client raised the prospect of her trying out for a talent ID day it was a challenge she could not resist.
"I knew that I could be good at cycling," she said.
"I found the spin classes easy and I was curious to see how I would go because I'd never been on a tandem before.
"I was excited about the thought of doing something competitive, which is why I went along in the first place."
Finding fun in riding a tandem on the track, Foy, who in early 2013 had moved down to Wellington to start a diploma in design, adapted seamlessly to the elite para-cycling programme.
Initially focused on road events, she quickly secured some encouraging results in World Cup races before she landed that bronze medal in Baie-Comeau, Canada at the Para-Cycling Road World Championships, where she also finished fourth in the Road Race.
"In the pre-championship camp I knew we were in good shape and we had a chance of a medal," she said. "But to win a bronze was pretty amazing."
In the wake of her success, PNZ opted to team the experienced Fairweather - the triumphant pilot alongside Gray at the London 2012 Paralympics - as Foy's new pilot and their attention switched to the track. The move proved inspirational. The combination quickly gelled and the pair revealed their prowess in the velodrome with 3000m Individual Pursuit gold and Sprint bronze in the B (visually impaired) category in Mexico.
Splitting their year in six months chunks between track and road, the combination feel primed for another prominent showing at the Para-Cycling Road World Championship which began in Greenville, South Carolina, this morning.
"We've worked on a few things in training and our preparation has gone well," says Foy, who trains out of the high performance base in Cambridge. "If things go well, hopefully we have a good chance."
Foy's chief focus in Greenville is the time trial - a 25km route she has already had the advantage of riding thanks to of modern technology.
"We have a computrainer in Cambridge which helps simulate the race course and I've ridden the course on the trainer a few times.
"I think it will be a good course for us because it is quite hilly and technical," she says.
Now aged 25, Foy was a relatively late arrival to the sport. Does she harbour any regrets she did not get involved earlier?
"I think my whole life I've been working towards [being an elite cyclist] without realising it," she says.
"Starting at an earlier age would have given me more time to develop, but as it turned out I believe I am at the right place at the right time."
