I work for a small (~60 people) tech company. There are two of us who ride regularly to work. I'm old enough that I don't really care what others think of me riding. Most seem impressed that I ride 60+km per day and a few muse about starting to ride to work (but no one seems to follow through).

I park my bike by the back door where there is an awning that keeps off most of the rain. There's plenty of space inside but I don't bother as it seems safe outside. We have a decent shower facility that I leave a towel in. We are a casual office so I normally stay in my cycling clothes for a while until I dry off and then have a shower. Before I go home I'll change back into cycling clothes in my office.

I think my situation is ideal. I get 9-11 hrs/wk of decent training just riding to work so my commute essentially costs me nothing in terms of time and I enjoy riding past the cars gridlocked on the bridge every morning and evening.
