I wear bike clothing and/or wool on my ride in. I think I sweat more during the winter because my yellow cycling jacket doesn't breathe worth a damn.

I'm one of the lucky ones. I get to work, drop my stuff off at my desk, and then walk down to the cafe. (I work on a corporate campus). By the time I walk back to my desk I've cooled off, drop off my coffee and banana, grab my towel and go take a shower.
