So, I completed W6R3 this morning and am amazed that I managed to run for 25 minutes. I would never have thought I could do that just a few weeks ago. So proud of myself. BUT, I felt very light-headed when I'd finished and I developed a headache a couple of hours later. (A couple of paracetamol got rid of it.) Now, I assume this is because of dehydration. I did drink a lot after my run, but I wanted to ask the more experienced runners if there is anything else I should be doing to minimize light-headedness? I'm really enjoying the runs and I don't want to be stalled by headaches and wooziness.
