Before the penultimate stage, Magne was still leading the race, closely followed by Pesenti. Magne was not sure if he would win the race, because that stage would be over cobbles, on which the Belgian cyclists were considered experts. The night before the stage, Magne could not sleep, and his roommate Leducq suggested that he could read some fan mail. Magne considered reading fan mail before the race was over as giving bad luck, but one oversized letter made him curious. Magne opened it, and read a letter from a fan who claimed that Belgian cyclist Gaston Rebry (who had won the 1931 Paris–Roubaix race over the same cobbles) had written to his mother that he was planning to attack on the penultimate stage, together with Jef Demuysere. Leducq thought the letter was a joke, but Magne did not take the risk and told his teammates to stay close to Rebry and Demuysere.
