PM - late start for a lunchtime run. Very cool by Florida standards (low 60's less than 50% humidity) - but I wasn't feeling it today. In fact as I started off, I felt like I had tweaked something in my left calf muscle - and stopped and then began again slowly. Seemed to be running along fine until about 7 miles when it started really becoming painful again - so I ended the intended 10-11 miles at 9 and used the foam roller in the gym to try to stretch it out. Feels like it may be lingering from skiing last week in the ski boots where you kinda press forward against your shins. Odd though that I have not had anything in the way of severe soreness there since then. Will keep an eye on it, and may give it a days rest or cross train tomorrow instead.
