Rather than the full commute, I opted for a 10 minute thrash in the rain to the train station and then through Manchester to work. Whilst I don't particularly mind getting wet if I can stay warm, arriving at work soaked and getting changed in a toilet, with no clothes drying facilities other than a radiator by my desk, is not a pleasant experience. And wet clothes drying out can get a bit whiffy, which is bit unfair on colleagues in an open plan office.
If have arrived damp either with sweat or getting caught in rain on the journey, generally I can get them dry or dryish before the majority of my colleagues arrive.
