I'm a runner who never goes on an "exercise walk", but there are plenty of (non-injury) reasons someone might prefer walking:

- less strenuous

- much less fitness required to walk for an hour than to run for 30 minutes

- easier to avoid sweating while walking, which can be useful for some commutes

- easier to talk on the phone while walking

- easier to find someone to walk with you than it is to find someone who will run with you

The article was about making fitness easy and not about making fitness efficient. I 100% agree that running is more efficient, but I'd recommend walking to anyone who thinks "bleh/eww" at the thought of exertion.

Plus it's great for either recovery days or a supplemental activity to get blood flowing to promote healing. For example running in the morning and walking in the evening.
