Sir Chris Hoy’s retirement marks the end of a remarkable career.His contribution to British sport & 6 Olympic golds will continue to inspire
Britain's most decorated Olympian, Sir Chris Hoy, has described being "lucky" to be part of the London 2012 Olympics and said he will enjoy being a spectator at the 2014 Commonwealth Games in Glasgow.
British Cycling’s President Brian Cookson described Sir Chris Hoy's impact on the sport as "unparalleled" and said his achievements have inspired thousands of people to cycle.

Chris has always been a fantastic role model – his professionalism, passion for the sport and his determination to succeed at the highest level is central to the Great Britain Cycling Team ethos and is something that he has helped to foster amongst his colleagues as they look ahead to Rio. This truly does feel like the end of an era and we have a lot to thank Sir Chris Hoy for at British Cycling.
Sir Chris Hoy said that the first thing he plans to do after retiring from competitive cycling was "to let it all sink in."
The 37-year-old told reporters said that in the immediate future he would be concentrating on his role as an ambassador for the youth Olympic bid for Glasgow for 2018 and for the Glasgow 24 team games next year.
He said he is also giving his time to Unicef and the Scottish Association for Mental Health and a range of other charities, as well as working on a range of bikes.
Sir Chris Hoy said he is stepping down today because it is time to let a younger rider shine.
He told reporters: "Nothing would have given me more pleasure than to continue on for another year, to be there in Glasgow to represent Scotland, to be part of the team.
"But I just feel that I don't want to be there just to make up the numbers I want to be there to be competitive and being objective about it I realise I got everything out in London, so I think it would be better to let a younger rider come through to give them chance to shine."

I am officially announcing my retirement from official competition today.
It's not a decision that I took lightly or came to easily but I know it's the right time.
