What horror stories are those Jason?
Flu is an odd thing. I've had proper flu once in my life. Standing up was out of the question. I've also heard recently that they now believe some people can actually have mild flu and just have symptoms of a mild cold.
I ran Rutland on Sunday with a head cold, runny nose, slight sore throat when I went to bed but just bunged up when I woke up. After the first few yards my nose started streaming and cleared. Hypothermia was more of a concern to me.
