 Thurau's primary goals for the next season became the 1978 Giro d'Italia and the 1978 UCI Road World Championships, and his team skipped the 1978 Tour de France, because they felt there were too many mountain finishes for a rider like Thurau.Although Thurau won two stages in the 1978 Giro, it did not go as expected, as he had to abandon the race in the tenth stage, when he had already given up all hopes for the general classification.In 1979, Thurau won Liège–Bastogne–Liège, and again came second in the 1979 UCI Road World Championships, but he was no longer seen as able to win a grand tour, and he changed teams.
