"The sense of pride, the satisfaction has been worth it without a doubt," Laybourne told BBC Sport of her London 2012 experience. "But I have to be able to put a roof over my head, to support myself and potentially a family in the future."
Retirements are par for the course for top athletes, whether they are brought on by unexpected injury, a cut in funding, or simply the natural end to a competitive career.
At 30, she immediately knew her competitive career had ended.
"I was very well supported by my sport in terms of my transition period, but it was not easy to go through," she said.
"You have had this one goal for so long and never questioned it. Then suddenly it's not there anymore."
The two-time European champion and former world number one found herself unexpectedly searching for some form of paid employment.
"You are used to aspiring to be, literally, the best in the world," she said.

"But you have to make compromises. What is success in the normal workplace and what does success mean to me?"
Harland experimented with jobs away from sport, but quickly realised she wanted her future to have some form of sporting connection. Now she finds herself employed by the BOA as a sport engagement manager, responsible for the team that organised the career fair in Reading.
"I am an ex-athlete and went through this process myself," she explained.
"At the fair, we had the British Olympic Association, the British Paralympic Association, the Institute for Sport, UK Sport and the Dame Kelly Holmes Legacy Trust. We all recognise that there is that responsibility to ensure that athletes are supported during what is a very difficult time."
England and Great Britain hockey captain Kate Walsh knows all about that difficult time.
In 2007, her sport's funding was cut. Then, after London 2012, a gap in funding provision meant almost her entire squad has had to look for paid work elsewhere.
"We all had to go out and get jobs," she said. "That took some time.
"It's really scary for some athletes, devastating. We've all got rent and mortgages to pay."
Georgina Harland (above) is a former Olympian and now works for the BOA. She tells BBC Sport why ex-athletes make excellent employees:
"When you are in sport you are surrounded by driven people every day. In business, to have that drive and goal-setting, plus dealing with pressure situations, are very desirable skills in the workplace.
"There are all sorts of natural skills that athletes just take for granted - self-confidence, leadership skills, decision-making. But they are actually very sought after."

has represented her country since 1999 and participated in two World Cups, three European Cups and two Commonwealth Games.
She does not intend to retire from her sport yet - and has found part-time work in public relations for a firm in Berkshire.
The Team GB captain is frank about how balancing employment and an ongoing playing career can be far from ideal.
"There will be hard times when you have to train in the morning, go to work, train in the evening," she said.
"You have to squeeze it in, do it during the lunch hour. That's far less ideal than doing your training and being able to recover properly."
Harland is sympathetic to the plights of those out-of-work ex-athletes.
"Don't panic" is her advice.
"There is time to make mistakes in terms of finding the right path now. You may start something and realise it's not the job for you. It's all right.
"You can find a job that will satisfy you. It may never be what it was like when you were competing, but you can find something that satisfies in a different way."
