Injury

After Sunday's run my knee seized up during the day for some reason. I thought the problem had gone away but it clearly hasn't as I had to abandon tonight's effort after a few hundred yards. Its an IT Band injury of some sort which has emerged from nowhere. Hugely frustrating as I don't know what's caused it and I was looking forward to getting back into training. There's no good time to be injured but I suppose immediately after a marathon is as good as time as any since there's plenty of time to get over it. So, enforced rest for a few days, some stretching of the band, and hopefully I can get back to it without too much delay....
