A former McDonalds worker who struggled to run to the end of her road has qualified for Team GB's duathlon team.
Lizz Davidson, from Southport, Merseyside, was overweight and could barely run the length of her street at 24-years-old.
But after overhauling her lifestyle, she dropped six stone and found a love for training leading her to take part in her first triathlon with friends in 2009.
