Hi, completed week 5 run 3 a couple of weeks ago, I couldn't believe I'd done it, it wasn't easy but I got there and it left me thinking maybe I really can do this! However it wasn't all good as it left me with a really bad headache as did the previous 2 x 8 minute run. I have since seen my GP who encouraged me to continue running and said it very much looks like migraine due to either the exercise or something I have eaten. I have cut out a couple of things from my diet and have avoided the longer week 5 runs. So far so good, and so I want to try the last run again and hopefully move on to week 6 but I am a bit apprehensive in case the headache comes back. Has anyone else had a running headache?
