From what I've heard this is a very popular ride. The folks over on the bike journal have a thread in the forum about this ride. (www.bikejournal.com).

Drink, drink, drink. Don't forget to eat, but eat often rather than just at the rest stop. My understanding is that if you drink or eat/drink something every half hour, you'll have more energy for the entire ride.

I use Jelly Belly Sportbeans for my electrolyte replacement. They work well as do Endurolytes. If you REALLY get in a pinch, ordinary table salt will stop cramps. I always carry a little bag with salts I pick up at fast food spots.

Have a great ride. We'll be anxious to hear your report!
