Last night I tried Gu for the very first time. It went OK. I was worried from the horror stories that I wouldn't be able to swallow it or that it would make me feel really thirsty. It actually increased my saliva by a bit. I did it at the turnaround, at the bottom of the Holmes Lake Dam (the Damn Hill) and drank about half a bottle with it. Brian will be watching for a case of it to go on sale.
Post ride I was miserable for awhile, lots of right leg tightness and some calf cramps that didn't really resolve with liquid. After a hot shower I felt more human and I slept like a rock. We'll see if the rain cooperates with me riding today.
