I don't disagree with you. Each person is different in the amount he perspires, the amount he drinks throughout the day, etc. If I were riding for 2+ hours in the winter, which, by the way, I won't do anymore, I'd bring along one bottle of water. But that quarter bottle of water hasn't been touched in over two weeks, and it's only November!
Also, I routinely run 90+ minutes early in the morning right after waking up, and without a sip of water. I wouldn't recommend anyone else doing it, but I've learned this much about myself over the many years of training.
