I biked the trail in August of 2006. The temperature hovered right around 100 degrees the entire ride, topping out at 104. The first two days were torture because I drastically underestimated my fluid needs. But the last two days were cake once I figured out a hydration method that worked for me. I stuffed my camelbak and two spare bottles completely full of ice, then filled up with water and powdered gatorade. I put the bite valve in my mouth and didn't let it drop until I stopped riding. I drank slow small sips constantly all day. I never went more than a few second without taking a sip. I think that going solo helped me to stay better hydrated than people riding in groups, because I didn't have to worry about talking to anybody. I could keep the bite valve in my mouth all day without it ever getting in the way of a conversation. I topped off at every trailhead to assure I wouldn't run out. I tried alternating one camelbak of gatorade with one camelbak of water, but the water just didn't replenish me enough in such extreme heat. I felt much better when I stuck to gatorade, so I drank it constantly when I was pedaling and switched to water after I stopped for the day. Believe me, if you hydrate yourself correctly, you will be amazed at what you can do! During those last two days of 100 degree weather, I rode faster than I ever have before and barely seemed to notice the heat or the miles slipping by.
