"It's hard for any sportsman or woman to get to the top of their game but I marvel at the guts and dedication it must take if you are born with a disability - or become disabled through accident or injury. And as parents blessed with four healthy children, Victoria and I are humbled by the strength and energy of mums and dads who encourage their disabled children to take up sports. It can involve real hardship and sacrifice - but there is no greater life lesson you can give your kids than to be the very best you can."

Speaking on Britain's The Jonathan Ross Show, she said, "He's an ex-rugby player and now he's training to be a sprinter. So I live with an athlete... Since the Olympics I have been working out a little bit, I think it's got everyone inspired...
"He's got me sprinting. We go to the park and he'll be like, 'Run to me' and I'll get halfway and think, 'Oh, I'll just walk the rest of it', and the look on his face is like pure disgust that I've not finished. It does not occur to him that you wouldn't finish something."
