As part of my training programme for the half marathon I do one large run a week.
I have been getting a bad headache afterwards, that slowly gets worse and worse, to the point that I can't function and need to go to bed.
I understand the need to hydrate properly and take electrolytes before and after the run, as well as drink large amounts of water to try and get rid of the headache.
These headaches are quite common for me after I do any exercise that requires me to push myself. For example I did a Tri-Triathlon earlier in the year and ended up with a massive headache afterwards.
I drink about 2 litres of water most days.
I really want to sort this out as I am really enjoying the challenge of training for the half marathon, and look forward to competing.

Angela, it is possible you are over hydrating. This will cause bloating of your tissues which includes the brain. For most of use there is little spare space within the skull for any expansion. This will cause a splitting headache
