I'm not sure he'll make it. And I'm happy to be wrong here.
The first time Wout got to it in his first race, yes yes I know they're different rider sizes and types, but he got beaten on it.
It will be tough for Pidcock to hang on when the bigger riders lay down 500w on the flat, but should go well on the climb if he is still in contention.
I think Alaphillipe is the lightest rider to have ever won the race. (62kg)
Pidcock on that final climb could be fun
