I'm 41. Been at this for years. I am "customer facing", meaning that I attempt (at least) to look good at work. I take the clothes in with me daily. I leave shoes at work. I shower at work. I take anywhere from 45 mins to 1h15m, depending on course.

I run a lot and view the combo of biking & running as the ultimate cross-training. I had a nasty case of plantar f...itis from running last summar and biking saved me from turning into a marshmallow.

Biking affords you a level of anonymity, but I've been at it so long that everyone knows me and my bike!!
