The last two road rides I've took after resulted in this nagging headache that I cannot shake til I go to bed and rest for 8 hours. It's only started since the weather turned cold (50-60 deg.) and the air has become drier.
I feel like I'm hydrating properly and my recovery meals are better since I feel when this is about to start. It always takes @ an hour for it start, but once it starts, it continues. I've taken Advil, eat a little more and sucked down water to try and 'remedy' the situation.
The only thing I may be lacking, but it hasn't mattered other times during the summer, was a better breakfast. I haven't eaten that much before we left on the last two rides.
I used to go through this in the summer, but this past year I was fine during the transition from winter to spring to summer. I do remember this type of headache a couple of years back coming around more commonly during the fall.
Any ideas, suggestions, antidotes as to why this is happening and what I need to adjust?
