This is especially good advice. Once I figured out the nutrition for long rides, they got much easier. Biggest help for me was a light breakfast (in my case, a smoothie is preferred) at least 2 hours before start, and then start eating as soon as I get on the bike. Consistent calories each hour of the ride and I am good to ride. On a century, I usually get in my head about mile 80, regardless of my fitness level, but I'm always glad I did it once I'm finished.
Good luck and keep updating. I'm looking forward to reading about your training.
