Floppy-joint running

A few days ago my wife was remarking that my running looks totally relaxed. I acknowledged that I follow the same precepts that help me so much when I ski, I try to stay as loose as possible in my joints, especially hips, knees and ankles. I'm also making a concerted mental effort in thinking I'm light and that I'm barely touching the ground, as if I were floating.

This of course is easy for me to say and put into practice when I'm running with my spouse who, by virtue of her gender alone, suffer the same handicap women do when dealing with men, a significant difference in performance due to weight and muscle mass. When I push myself, lightness yields to brute force and at that time, all these loosy-goosey benefits vaporize...
