I currently have a pulled muscle in my calf. It went during the warm up last Friday (but, it had gone previously to that). So, as it's been recurring I haven't done any training for a week. I'll go back tonight but, I won't do any jogging.
This has put a big hole in my training! Grrr!
Anyway, it's the 2nd grading of my students this Sunday - so I need to focus my attention on that.
