I've just completed the second run of week 8 and found it tough from start to finish. My breathing was awful, I was gasping at some points and my legs felt like lead. I'm home now but with a headache and dizzy. I was going to put it down to running in the morning which I don't do as I prefer afternoon runs...but I think I'm getting a cold or something. Surely morning runs can't make you feel that bad?
