I've had a headache since Friday evening which has meant I missed a run at the weekend and a session in the gym tonight. It seems to have gone now, thankfully. I've got a feeling it was linked to dehydration. I do seem to be drinking a heck of a lot at the moment but still feel very thirsty. Perhaps it's something to do with the increase in temperature. Who knows!
The good news is that I'm desperate to go for a run tomorrow and will be doing 2 or 3 short easy runs before the Chevy Chase on Saturday.
