Video: Tour de France stage 20 preview with Chris Boardman

It will be a historic day for the Tour de France when the peloton rolls onto the Champs-Élysées with a British rider wearing the maillot jaune. Bradley Wiggins (Sky) will ride into Paris as the first rider from Britain to win the Tour de France but he will still have to keep out of trouble as the peloton races towards a likely bunch sprint.
