Running form. Lets not watch the clock so much today, and concentrate on breathing. The ideal breath ratio is said to be 3:2. That is breath in for three steps, breath out for two. Play with it. find what's right for you. If I don't pay attention I end up doing 2:2 and running slowly and out of breath. I have to tell myself "breath in left, right, left, breath out right left. In, 2,3, out, 2, in 2,3, out,2 . . . etc. While your at it make sure your back is straight, your shoulders are loose, and your face and hands are relaxed. the idea is to send all energy to the legs. Tensing your face, shoulders, hands etc is a waste of energy. Once you've got all this down try picking your knees up and lengthening your stride. Also look at your toes, try running with them pointing straight forward maybe a touch inward. Do these things and the clock will take care of itself.
