Laura Trott, who is preparing for the London 2012 Olympics where she is expected to become one of Britain's youngest medal winners, has her mother to thank for her success.
Desperately embarrassed by her size 24 figure, the Olympic hopeful's mother Glenda Trott took her young family to the local cycling track.
AdvertisementShe could not have known that in doing so, she would set in motion an extraordinary chain of events that would see her daughter crowned a world and European cycling champion.
In 2000, teaching assistant Mrs Trott was mortified when she was told she was too heavy to get on to a cable car while on holiday with her family in the U.S.
She took her husband, accountant Adrian, and daughters Laura and Emma, then eight and 10, to the local cycling track, hoping to get fit with her young family.
As a result, she lost seven stone in a year - and introduced her daughters to a sport they loved and excelled at.
"My mum really wanted to lose weight and a friend suggested that she try the local track at Welwyn Garden City. We all loved it. It was something we did as a family and we would go out on the bikes together. Soon I was spending every week on the track," the Daily Mail quoted Laura as saying.
Glenda also spoke about her motivation to lose weight.
"I needed to do something about it. I was in tears a lot of the time," Glenda said.
"I put on weight after I had the children. Their school was literally a five-minute walk from our house but I would drive them to school because couldn't even walk there. I would get out of breath.
"I remember walking into a shop and I could only fit into maternity wear. That's when I decided I had to do something about my weight.
"My doctor told me to try swimming but I couldn't face having people looking at me. My husband bought be a bike instead and one day we went down to the track. And that was it. Laura and Emma were off straight away," she added.
Her steely determination also inspired her eldest daughter Emma, 22, who is a professional road cyclist in Holland.
