Without going into great detail, here are the 7 key points I make in teaching someone how to run:
7) Finally, faster cadence is not the answer! Cadence and foot strike may be correlated, but we all know from our science and statistics classes that correlations are not cause-effect. Go down to the National Mall and watch hundreds of heel strikers with a cadence at 90+ RPMs (or 180 if you're counting both feet). I would even argue that the faster cadence often promotes heel striking, and I make this point explicit in my 101 sessions. If I can get someone into a midfoot strike, but with a relatively (key word) slower turnover, then that's okay because correcting cadence takes much less work than correcting foot strike.
