Do it! So much better than any other way to get to work. easy on the way there. Take some wipes and some deo as your fellow collegues will appreciate it.
On way back do eyeballs out. Its not going to hurt your fitness.
Mine is 4 miles to work and then go the longer way back and get a couple of hours ride on the way back.
Used to run it before getting injured and was a free 40 miles running training a week before specific club training.
I now wouldn't consider any other forms of getting to work apart from bike or run.
