I'm training with my brother at the mo for a HM in January. I seem to have started to struggle on the longer runs with dehydration, at least I think thats what is causing me to have horrendous migraines (which I do suffer from but normally the tablet I take keeps them at bay). After running nearly 8 miles on Saturday averaging at 11.51 m/mile, I felt very ill all of Saturday afternoon/evening with a migraine and I really don't want to think about giving up on the whole HM idea. I'm wondering if maybe I did too much and ran too fast?? It was a mostly flat course and one that I've ran hundreds of times now only just a bit further on to loop back.
I took water with me and drank all of it by the time I got back, I had eaten a bowl of porridge and a piece of toast with peanut butter on so felt I had prepared although maybe I could have drank more water before I went out.
Any ideas??? suggestions???
