I'm still mystified to how I did it, but I've strained my calf muscle in my left leg. I'm starting to think it was my very enthusiastic sprint at the end of my last run on Wednesday but whatever it was I daren't lace up my trainers till it's completely pain free. It only hurts now when I squeeze the muscle, so couple of days I reckon. Yoga today then...
Oh found out my left leg overextends, never knew this till my Yoga teacher pointed it out! Funny it's always this leg that I've had the problems with...maybe there's a connection there??
