In the ninth stage, Gaul tried to do the same again, and got over the first three mountains alone. But because of a crash on the second mountain he lost time, and did not win the stage; instead he even lost a few minutes. During the eleventh stage, French cyclist Jean Malléjac collapsed and remained unconscious for 15 minutes. The Tour doctor who helped recognised that Malléjac's symptoms were identical to an amphetamine overdose, and told the team doctors to be more careful with doping. In that stage, Bobet got away on Mont Ventoux and nobody was able to follow him. He reached the top alone, and from there descended to the finish, 6 minutes ahead of Rolland, who was still the race leader. Bobet jumped to second place in the general classification.
