Re: POSE technique and calf soreness...
I'm a self taught POSEr too. My calfs were extremely sore for about a week when I first got my racing flats and tried POSE. I've seen this posted many times over on the POSE discussion boards. What I found was that yes, there is an adaption period. One thing that I was warned of was trying to keep the heel too elevated placing too much stress on the calf. If your heel brushes the ground that is OK, it just shouldn't bear any weight. Someone who has been to a clinic or cert may tell you otherwise, but that has been my experience.
