Well, this is annoying. Another test run yesterday to check out the calf went rather less well than I hoped. Feeling fine at the start I ran carefully, of course, but after two kilometres the pain returned, severe enough to throw in the towel a little short of three kilometres. The rest of the day and now, the next day, the calf is sore and tight. Clearly, I am going to have to give this complete rest to recover fully.
This is really frustrating, as my running was going well and it was only a slight strain, yet it seems to want to take days and days to recover.
It seems I am going to need to be far more cautious than I ever thought necessary before. Lucky, therefore, that I started this campaign nice and early. It's a setback, but only a temporary one.
