Fans might have been puzzled to see Mathieu van der Poel step onto the podium of the Tour de France in the yellow jersey after stage four, rather than the man who had just won, Tadej Pogačar.
It was all because of a little-used rule called count-back, meaning Alpecin-Deceuninck’s Van der Poel will remain in the race lead for a third day, while Pogačar of UAE Team Emirates-XRG will have to wait a bit longer to get his hands back on the maillot jaune he has worn so many times before.
