A big enough.How big of part play the cobble sectors in PR anyway?
The tricky part will be to get them to stick to the non-flat parts at the ends of the velodrome.Couldn't they just drop some cobbles from Carrefour de l'Arbre onto the velodrome from a helicopter?
If cobblestones falling from the sky isn't classified as extreme weather, what's even the point of the protocol?I don't think it's in the extreme weather protocol though.
Gonna be a bit awkward if anyone lives somewhere with shared washing machines.I propose that Paris - Roubaix takes place in Zwift this year. To simulate the cobbles the riders should put their bike stand on top of their washing machine, who would periodically be put in centrifugation.
Surely the fans in Belgium at least should be knowledgeable and respectful enough of the sport to stay at home and watch on TV thus not endangering the chances of the events taking place.
