I often ride between 15-28 miles in to work at a good clip. I leave clean clothes at work (take them in once a week on the bus.) I take a shower before I ride, put my wet hair in a ponytail. At work, I change in a stall (there's a shower but no hot water so...) and use a damp washcloth to wipe down, then air dry or dab with a big towel (that I also leave at work.) I spritz with a body spray and brush out my hair. Usually on ride days it goes back into a ponytail. Anyhow, I don't smell sweaty even after a long ride on a humid day.

My friend Martha who rides with me works in a building with no shower, and she is an investment banker and so must wear a suit. She just uses baby wipes. My problem with baby wipes is that they are disposable. She keeps her clothes in a file drawer in her office, and changes there (with the door closed.)

After doing this for two summers it is worthwhile to note that getting to work 15-20 minutes early means that you stop sweating while you are calmly changing in the bathroom. Be sure and give yourself plenty of cool-down time.

Nonbiking friends say, "I think that's great but I couldn't give up 4 hours of my day for that kind of commute." To that I say, you'd rather drive and sit in traffic for 2.5 hours a day? Then haul off to the gym after work to wait in line for the ellyptical? Then shower in the gym shower? I'd rather ride!
