Excellent job!
I am doing very well on my three day a week commute (I only go to the office that often, pardon me for refusing to go just to bike...)
What a difference in how I look and feel after 4 months or so. Now I am starting to go on fun tours on my days off. Sort of guilt free exploring. I can go pedaling along for hours and not worry about gas prices, repair to cars or anything. Food costs are another thing though.
