Dumb running technique

Here's my running discovery for the day.

Some weeks back, I tried to dis-engage my lower torso from my upper torso when running; meaning, let the legs do all the world whilst everything from the waist up remains utterly relaxed.  What better occasion to prove this wrong than on a LSD - after 2k, I realised the arms play such an important role in maintaining forward momentum with the legs that I totally gave this running technique up.

I tried a variation tonight.  Everything from the shoulder up is disengaged from everything below.  The legs work in unison with the arms but the shoulders and head are totally relaxed.  No clenched teeth, and let my thoughts wonder.  It worked - my breathing was not laboured, I did not feel the burn in my legs and I actually focused on a proper toe-off and heel lift; but its too early to call success until the next run.
