Those guys who arrive to work as sweating soggy messes need to slow down. After all, I'm going to rest at a stoplight sooner or later anyway. I'd feel disgusted if I had to breath in other people's stench from an air conditioner in a small office. I hope they wear deodorant because nothing is worse than a bicycle commuter who reeks of BO. It helps that I keep a change of clothes in my backpack/office that I can change into.
My 5-7 mile morning commute I don't mind cruising at 15mph in the morning, it still wakes me up and I feel refreshed all day. I can save my workout for my trip home. My shower will be ready after my ride : )
