In the seventh stage, the peloton broke in two, and a large group of 31 cyclists finished more than 18 minutes ahead. This group included Roger Walkowiak, who had also been in the escaped group in the fourth stage, and became the new leader. Walkowiak's team manager, Sauveur Ducazeaux, advised Walkowiak that it would be too tough to try to remain the leader for the rest of the race, and suggested that Walkowiak lose the first place, and aim to regain it later in the race. In the tenth stage, Walkowiak lost time, and Gerrit Voorting who had also been part of the large breakaway group in stage seven, became the new leader. Voorting lost the lead in the next stage to Darrigade, who himself lost the lead to Jan Adriaensens in the twelfth stage.
