Sir Bradley Wiggins on the Olympics & Tour de France

2012 Tour de France winner Sir Bradley Wiggins is "concentrating on 2014" as he aims to be back "winning races, being happy".

Having failed to defend his title in France last year, Wiggins is determined "to get back to where I was in 2012".

In the final year of his Sky Pro Cycling contract, Wiggins sees himself as part of the "fabric of the team".
