I started a couple months ago... it goes a lot faster than I originally thought it would. I have the luxury of being able to toss my bike on a bus and knock 13 miles off that 16 mile trip for about a buck. For a while I would bike halfway and bus the rest. But then I just started doing the full route and it wasn't so bad. One thing about biking. It gets easier, and it gets faster. There are hills on my route that three weeks ago were daunting, but now I'm taking in middle gears at 10-12 miles/hour. It will come... just keep at it.
