Michael Johnson

Kirsty Young's castaway is the athlete Michael Johnson.

He is the only person ever to hold world records in the 200 and 400 metres at the same time and, by the time he hung up his legendary gold trainers, his haul of medals included five Olympic golds.

His upright running style earned him the nickname 'the duck'. He says: "They called me a really fast duck! I was ranked number one in the world - I'm so far ahead of the other people, why am I the one that's wrong?"
