I'm bringing running back....

This morning I ran for the second time this week. Only 4 miles and I can't say they were particularly comfortable. It was rainy and miserable and my head was throbbing after about 5 minutes. I'm nervous about it but I'm thinking I will run the half marathon next sunday. A few people have said really unhelpful things to me like - surely you just keep running? I have resisted the urge to make a snarky reply such as - well couldn't someone have told me that before I started these 5 months of training? I'm going to keep positive. Because really all I have to do is just keep running, just keep running, just keep running....................
