I've had the same route to work for 23 years and have bike commuted for 19 years, 75% of the time - I take public transit the rest. Today for the first time I walked the whole 8 km to work. It took 90 minutes and was a beautiful, slightly cool but sunny day. You see a lot more on a bike than in a car, and even more on foot. I noticed some new details on a route I have biked several thousand times.
I took the subway home since my legs were sore. Not just from the walk. but from taking up running this year and doing 5 k Monday.
No running tonight!
