OP here. Rode 65 thus a.m. In about 4:30 ride time, 5 hours overall. Didn't try stress on anything. Hydration was okay but only because I passed mini-marts where I could buy more water! Nutrition seemed okay, a power bar and another type of "nutrition bar", need to work on that. I'll try PBJ this week though it seems it would make me more thirsty.

Thanks for the advice and encouragement.
