The next stages were all flat, and the favourites were unable to gain time on each other. In the fourth stage, a group without favourites escaped and won the stage with a margin of a few minutes; Jean-Pierre Genet was the best-placed cyclist of that group, and became the new leader. A similar thing happened in the first part of the fifth stage; Georges Vandenberghe was the only cyclist who had been present in both escape groups, and he became the new leader of the general classification.
