'I believe I'll be the athlete I once was'

Former GB runner Bobby Clay has revealed how over-training as a teenager left her bones so weak she had nine breaks in her shin.

Too much running and not eating enough meant the 20-year-old didn't start her periods - which led to osteoporosis.

Now, thanks to hormone replacement treatment, she is now back training and hopes to one day to get back to the level she once was.
