Since high school cross country in the 1970's, we were told the proper distance running form is rolling heal-to-toe, while for the short distance sprinters the form is to land on toes or the balls of the feet. This could be one of those shockers where something I've learned turns out to be false.

Still, I'm still finding it hard to imagine running, say, ten miles by landing on the front part of the foot and not the heal first. Maybe we humans aren't naturally evolved to run ten mile distances. I give it a try, but I suspect I'll be a heal-to-toe distance runner.
