Olympic silver medallist and former world number one Heather Fell has announced her retirement from modern pentathlon.

Fell, who became the fourth British athlete to win a medal in the sport when she took second place in Beijing in 2008, intends to pursue a career in the media.

The 30-year-old from Plymouth said: "I've had a wonderful career in a sport I love. I never imagined I would be able to have the opportunity to train full-time for my sport.

"I take so many happy memories with me. I'm now turning my attention to a new and exciting career alongside the different physical challenge of road cycling."

Jan Bartu, Pentathlon GB performance director, said: "I'd like to wish Heather all the best for the future. Her successes from her time as a junior up to Olympic, World Championships, World Cups and European Championships speak for themselves. It will be sad to see her go.

"Heather has been a very strong athlete and in many ways her competition performances often exceeded expectations from training. That's almost unique, it's something not many athletes can do. I would never underestimate Heather's desire and will to succeed, which have been inspirational."
