Extreme training paying dividends for Wiggins

A combination of a course that suits him and the stunning form that he has shown over the last nine months has led many observers to the conclusion that this could be the year that Bradley Wiggins makes history by becoming the first British rider to win the Tour de France. As is seemingly and regrettably inevitable with cycling, with improved form comes whispers about how it is achieved. Cynicism is never far away. But Wiggins is paying it no attention and is pretty explicit about the secret of his success. And you can hardly miss it - it's a big volcano in the middle of Tenerife.
