Denise Lewis, Olympic gold medallist, is Kirsty Young's castaway.

Her discipline was the heptathlon and it was at the 2000 Sydney Olympics that she leapt, threw, sprinted and hurdled her way on to the winner's podium. An only child of a single mother, she says her mum had always had ambition for her - and was there to witness her success. She said: "Her face said it all, there were tears in her eyes and for me it felt like, yes mum, we've done it together".
