FLORENCE, Italy (AP) -- It's not often that a Tour de France winner and multiple Olympic champion needs to learn how to ride his bike again.
Yet that's pretty much what has happened to Bradley Wiggins in the past year.
Wiggins is back in form after wins at the Tours of Poland and Britain, capped by a silver medal in the time trial at the world championships on Wednesday. Early in the season, he struggled during the Giro d'Italia and withdrew from the Tour de France because of injury.
He says, ''It was hard, it was challenging. I pretty much went back to the drawing board. ... I felt like a complete fall from grace.''
