My commute is between 5 and 15 miles depending on which bus I choose to chase (I am always late for the bus.)

I can't wear my work clothes. Too sweaty. But I do not wear bike shorts, either. I wear sweat pants or athletic pants with the ankle cuffed with a reflecting velcro strap. I have an ancient brooks saddle which is torn, and so it is covered with one of those padded seat covers. It is comfortable to 15 miles - after that it's very uncomfortable.
