I think it's fun. My main problem when running is that unlike when I walk, my inner monologue somehow gets silenced. It bores me to death. I try and compensate with podcasts (or a magazine on the treadmill) but it's sometimes better to just alternate.
What about music. Music takes less concentration, but takes away that bored feeling.
I like to walk in town. (I love to hike, but I have to get outta town for that.) I used to listen to nothing, worried about whether I could be alert to traffic. Listening to music, for me, was a dismal failure—I kept wanting to match my pace to the beat. I found listening to podcasts ideal, even when I have to stop to laugh.
I don't run unless I'm being chased, generally, although I do actually enjoy jogging on a mini-trampoline in my living room. (My cat finds this appalling.) I thought that would work well while watching TV...nope. I get bored and whiny. A carefully-chosen music playlist is great; I pick songs with the right tempo, and it's easy enough to say "c'mon, just one more song, okay, one more" and keep at it for half an hour or more.
I'm also planning on finding a place within walking distance of my job in Chicago, so I can get that walking time even on days when I can't make it to the gym. I think in the long run it will pay off.
I think that's a great idea.
