Hi gang. I've read some past threads on this, but wanted to revisit the issue. Yesterday was the first sunny and warm day in a while, and I had a great 42-mile ride. However, I developed a headache several hours after the ride. To be precise, the ride ended around 2:30 and I got the headache around 9. The same thing frequently happened last year as well.

I tried to stay hydrated yesterday before, during and after the ride. By the look and frequency of my, well, pee, I did a good job with that. I drank both water and a sports drink. I had some Pepsi later, along with more water, too.

I've taken two rounds of sinus medicine and some Advil and Excedrin for good measure. Since none of that has worked, I plan to take my migraine medicine when I get home from work (it was prescribed to treat menstrual-related migraines). I suspect it will help, although it will also more or less put me to sleep. I hate taking it.

So, what gives? I don't typically get the headache until after the ride is over. I wear polarized, dark sunglasses, don't overtighten my helmet or clench my jaw. I don't get headaches from working out in general and I don't get them, if I remember correctly, when I ride in the cold. Obviously, I'm thinking it's a hydration/heat thing. If that's the case, then I guess I need to push even more water/fluids than I thought.

Does anyone else have any thoughts? Could it be some kind of vitamen/mineral deficiency that's made worse when I sweat a lot? I will admit that I've been lax on taking my multi-vitamen of late....

Thanks for your thoughts.

Kate
