I was wondering if that was in Faulkner's head when she didn't celebrate crossing the line. Perhaps she didn't want to "do an Annemiek" and celebrate a non-win?
Arrivée by The Cycling Podcast says that she's done that before. It's almost becoming her trademark to keep powering through and not celebrate crossing the line. Not sure they know, or know why.
They also said that Vos in interviews claimed to have nothing left so couldn't chase, while Kopecky said that she thought Vos was bluffing and would chase, until it was too late. I suppose Vas wasn't required to stick around and give an interview, finishing fourth, so probably went to throw the bike in the river or something.
