point where it hurts. If you are pointing at your forehead, all the crap in the air is irritating your sinuses.
Try having something after a ride. I like a fruit shake. Basically you want water, come calories and some electrolytes if it's hot. You can buy a recovery drink mix like Endurox as well. Even OJ with a couple grains of low sodium salt would be worth trying.
Are there any other symptoms that go along with the headache?
Its usually just a splitting headache that comes about after resting for about a half hour to 45 minutes. There's no problem immediately after exercise though.
The intensity of the headache is almost proportionate to the exertion. Initially I thought it was dehydration, so I made an effort to drink up. But this doesn't seem to help. But then again, I may not be hydrating myself enough, so maybe it might be dehydration although I doubt it.
Although I've had issues with sinusitis in the past, I had this problem even when my regular workouts were limited to just the gym.
I was reading some of these healthwebsites and they mentioned something about exercise induced headaches. They don't really pinpoint a particular causing factor, but i'm thinking maybe it might be due to my fitness level or something?
