I have been thinking about hydration and am wondering what others do. I typically end up using one 20 ounce bottle of water/carb mix per 60-90 mins, depending on temperature. Unless it's really hot, I rarely seem to get truly thirsty, more likely hungry (which the mix seems to satisfy). For all I know, I'm dehydrated but I don't think so since my performance doesn't really fade over the ride (160 lbs, by the way).
Others?
