Thinking about doing the Great Birmingham Run on 20 Oct. I've done a local Fun Run 8k for the last few years but I'm an off & on runner not a serious one. I don't do any exercise at all in the winter (apart from extreme housework). I did 8.7k this evening in about 55 mins and felt fine. So what's the chances of me working up to do this half marathon and does anyone have any good tips? I don't have access to a gym so all my running is round streets & fields. I try to go 2 to 3 times a week but not if its too hot, raining, etc. Any thoughts gratefully received.
