The number of people that aren't used to riding in the wet! Some of them wasted so much time (obviously it's their choice and I can follow their reasoning) when they didnt come out to play until it dried out and those bravehearts that did were noticeably slower cos they're no used to it. Like Jools said, you get a whole new understanding of bike control in the rain, it takes finesse to ride a bike fast in the wet, I'm still practising as it makes you a smoother rider all year round
