Another descent to the finish followed in stage sixteen, and again the winner came from a breakaway. Boasson Hagen was the victor, improving on his second place the previous day. Overall race leader Voeckler lost 27 seconds to his rivals after he went wide on two of the final descent's corners. The Tour's queen stage, the eighteenth, included three hors catégorie climbs, including the Col du Galibier summit finish. With to go, Andy Schleck launched a solo attack on the second climb, the Col d'Izoard. He went on to bridge across and pass a large breakaway, before claiming the stage win; he moved up to second overall, gaining over two minutes on his rivals. Voeckler's lead in the yellow jersey was reduced to fifteen seconds. The autobus (the large group behind the leading peloton) of 88 riders finished outside the time limit, 35 min 50 s after Schleck; all riders were allowed to stay in the race due to the large number. The points classification leader, Cavendish, who was in the group, was docked 20 points.
