A trip to town

I had to ride down to London at the weekend and was pleased that I had managed to miss the rain on the 100 mile ride down...

Unfortunately I wasn’t so lucky on the return journey with thunderstorms and flash floods most of the way home

The thing I hate most about riding in the rain is when my glasses steam up and I can’t see clearly where I am going. Usually I leave the visor slightly open to prevent them fogging. Does anyone else have a solution for this that works?
