Jo did great in spite of feeling crummy and she was quite chipper!
My advice - figure out your nutrition plan. You have to make sure you stay fueled on your ride.
I don't like to eat solid food on a long ride. It took a while for me to figure that out and come up with what would work for me. On yesterday's 90 mile ride I only ate two bags of Cliff Bloks and two bags of Sport Beans. But I drank two full bottles of my Sustain/Gatorade concoction. If we had continued riding I would have switched to a Hammer Gel every hour, plus the beans and bloks. On a long ride I am very obsessive and regimented about my eating and drinking.
