Re: POSE technique and calf soreness...
Oy.... you are going to have sore calves whether you first start doing POSE/proper running right or wrong. There is absolutely no way to begin running with perfect form when you start out and your legs are not yet adaped to utilizing the stretch shortening cycle as a method of propulsion. Even if you are running POSE/properly under a coach's eye, your calves will still become sore because they are being used in an eccentric contraction 100x more than they ever used to be. It is inevitable.
