In the last week of the tour, Bradley Wiggins has distinguished himself as an outstanding sportman, and stamped his authority on the race. Partly with the assistance of the expensive and powerfully gifted Sky team - but mainly through moments of real personal class. First the reconciliatory gesture to Nibali after their epic battle up the slopes of La Toussuire. Then his willingness to act as lead-out for his team-mate Edvald Boasson Hagen at Cap d'Agde. And yesterday his sporting close down of the chase, allowing Cadel Evans time to rejoin the peleton after puncturing. He didn't need to do any of these things, but he did them whilst wearing the yellow jersey. And my surmise is that respect for him will have spread throughout the race as a whole.
