Sir Chris Hoy prepares for race at Snetterton

Britain's greatest Olympian Sir Chris Hoy was at the Snetterton circuit in Norfolk enjoying a rather faster set of wheels today.

Since his retirement from sprint cycling, Sir Chris has taken up motor racing.

He was practicing today ready for racing tomorrow when he will be driving a Radical sportscar in the SR1 Cup - billed as the UK's fastest novice race series.

Radical cars are built in East Anglia at Peterborough.
