Cycling (time trial)
Pooley won a silver medal in the 2008 Olympic time trial, an event in which she earned her first world title in 2010.
Inbetween those successes, she won the Grand Boucle Feminine, a race often dubbed "the women's Tour de France", and also ended Nicole Cooke's stranglehold on the national road race title.
She said after her silver at the 2008 Olympics: "I never planned to be a cyclist. My background is as a runner but because of the injury problems I started cycling as a way of cross-training and then I had a go at triathlon.
"I still considered myself a triathlete when I started road racing in 2005 - and I only went to my first few road races because a friend in my triathlon club persuaded me to go with her."
The Cambridge graduate put her PhD in soil engineering on hold to race full-time with the Cervelo professional team.
