Our expert says:
I would say that strengthening the calves is more important than stretching. If you do a static stretch, you're not really doing much in the longer term, whereas if you strengthen the calves, it will help them during the runs, because you'll probably find that this tightness is caused by the calves going into spasm. So my advice is to do calf-raises on the edge of a step, with your heel hanging off the back, and do three sets of 15 each day. They'll burn at first, so cut it at 10 if it's too sore, but that would be my suggestion (and I speak from experience, having the same issue as you!)
