If you'd like to point me towards current or recent research on the topic that substantiates your claim, please do. I'm always willing to learn something new.
My own claims are based on 10 years' worth of training and journal keeping in all four Mississippi seasons, wearing a GPS, most of it with a heart rate monitor. To test my insights, I've weighed myself before and after long runs to assess water loss, taking water consumed (or not consumed) during the run into account. I'm not just making shit up.
I listen closely to what my body is telling me. What it tells me is that when I run 14 miles on a warm, humid day and drink one 16 ounce bottle of water at 5 miles and a second bottle at 7 miles, I'm sweating more at 9, 10, 12 miles, and running more comfortably, even though the sweat isn't evaporating and cooling me. When I skip (or forget to stash) that second bottle of water, I run into trouble by 12 miles, I'm forced to slow my pace, sometimes quite a lot, and I'm not sweating as much when I do. It's about water loss--dehydration--and not overheating. Heat-provoked dehydration is the primary degrador.
Dude you're over analyzing things way to much. Drink when you're thirsty don't drink when you're not. There's a lot of good runners that don't drink at all or sparingly on long runs and are just fine. As long as you're well hydrated before you should be good to go in most situations. A few exceptions for the weather.
