Olympic cyclist Sir Chris Hoy was in Corby today promoting a lottery funded success story - the Adrenaline Alley BMX track.
It was created by Mandy and Paul Young in memory of their son John who died from a brain tumour.
Sir Chris is now the UK's most successful Olympian.
He spoke to Jonathan Wills and told him about his connections to the sport of BMX.
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.
