Ride MTB approx 32miles a week to work
32 miles is an approx. could be more by a couple of miles each day.
Ride 4 days a week at 4 miles each way.
I enjoy it because it is less sitting in traffic and even though I have to pack my clothes and change at work incl.shower or babywipes it is still less hassle, learn to work with it. Hot on the way home, I wet down my headsweat with cold water before putting on my helmet and keeps me cool till I get home to strip down. I feel good that I am not contributing to the pollution in the air.
Wish I were in Holland or somewhere there were were no cars at times. :p
