Is it really dehydration?

I'm hoping some folks have insight into this problem I'm having. I've been doing a bunch of training ride, some hills, some flat, generally 40-70 miles, 1-2 per weekend. I carry a camelbak and drink the whole thing (at least 64 oz on its own), drink tons of water, have electrolyte tablets, eat salty food, gu, honey stinger electrolytes, every ride. When I pee, it is crystal clear. And yet I have the same symptoms at the end of the day: headache, dry eyes, foggy brain/confusion, lethargy. Is there something I am missing? Is this dehydration or something else?

Could be several things. How frequently do you pee? When you finish the ride, how long before you pee? Do you have to drink a lot after the end of the ride before you'll be able to pee?

A common cause of your symptoms is low blood sugar. When I look at my computer and can't calculate how many miles I still have to ride, I know I'm low on food. On a 70 mile ride, I'll eat maybe 800 calories of mostly high glycemic index carbohydrate, plus having eaten a 400 calorie high-carb breakfast. One has to consciously keep track of the calories and try for 250 calories/hour.

Another possibility is allergies. It is spring, and cyclists strain a heck of a lot of pollen through their systems during a ride.

water. sodium, potassium have a delicate balance. it's easy to misjudge.
i was disappointed when i read the labels on some of the electrolyte chews I was eating. well, they tasted good at least. i am shopping now for a better answer.
not sure what weather conditions are like in your area, but if you are not getting sufficiently cooled off overheating can cause similar problems. so can sun overexposure.

I concur with posters above that it looks more like low blood sugar or possibly overheating than dehydration. You didn't specify what you ate before the ride and how much you ate during. The easy solution is to switch from water to a sports drink.

I usually have a chicken sandwich or veggie burger with a bunch of salty fries in the middle of the ride, and on the road, a few of those sugary "waffle" snacks that are like 100 calories each. So I think I am OK on calories.

I am in southern california so it can get warm, but hasn't been brutal. I think sun exposure could still be a factor, I think i'm going to get some of those "arm coolers" and "leg coolers".

I have to pee every couple errors while riding .. but after the end, yeah I have to drink a lot to have to pee anytime soon. So I could be lagging there.

thanks for the input!
