This is great stuff!

I especially like the part about our feet and whether not not people are "meant" to run. It's so important to develop proper form, and concrete and treadmills ruin this. Have you read Born to run?? It really hits on that topic. One of my favorite books.

I love running, but I'm totally the opposite about listening to stuff - just a distraction for me, I guess I just love to think. I like the aspect of really engaging my entire body and mind - sort of treating a run like a yoga session. I also find my clearest thoughts happen running. Everyone is different!

I live in Detroit, so totally know the whole cold running game too. I like to find basketball leagues to justify not running in the winter :)
