It's good that there are so many water stops. I use a Camelbak for stuff like that because it's so much easier to drink from it, thus I do so more frequently. I fill mine, then stop less frequently. I climb a little more slowly while it's full, but save much more time with fewer stops.
Best to get on with the heat training. Some of the weight that one loses riding is the unbound water from glycogen stores. As long as you don't lose more than 2% of your body weight, your performance shouldn't suffer.
On rides like this, I use the "I have to pee every 3 hours" rule. If I get into a rest stop 3 hours or so after the last one and can't pee, I sit in the shade, drink water and take Endurolytes until I do pee. Then I refill and head out. I think I come out on it, time-wise.
