running form ?

[Jo-n-NY]

First just a running form question. How do you plant your feet when you run. When I am on the treadmill I plant the ball of my foot. That is what feels natural to do. If I try to run outside, my heel is what goes done first. The book I am reading says to go down with the mid-foot. Working near the Westside Hwy bike/jog/walk path in Mahatten I am notice runners mostly going down on their heel. I was just wondering if there is a correct way.

Although I take lunch walks on the path, I am thinking of beginning my run/walk program during lunch 3 days a week. I keep cross trainer sneakers here at work for my walks, but I think I now should probably bring in fitness clothes. I probably have a few months before the lunch hour will be too hot to run. This will leave me time to take after work bike rides which I hope to begin at some point this month. I was wondering how I was going to juggle beginning a running program that would not interfer with my outdoor rides once the weather breaks for that. (to my satisfaction anyway

Sorry, my second paragraph is me thinking out loud but any input on my idea is welcome. hmmmm another thought, I guess I should get another pair of running sneakers instead of using the cross trainers for this.
