Flecha Brabanzona
Alaphilippe’s first race wearing the rainbow jersey was Liège-Bastogne-Liège, rescheduled to 4th October. He contested the five-man sprint and, believing he had won, celebrated as he crossed the line. However, a photo finish revealed that Primož Roglič had crossed the line in first place. Alaphilippe was later relegated to 5th place for impeding Marc Hirschi during the sprint. On 7th October, Alaphilippe took his first win as World Champion at the Brabantse Pijl ahead of Mathieu van der Poel and Benoit Cosnefroy, with whom he had attacked inside the final 20 kilometers.
