Thanks for the good responses. I have two metric centuries scheduled in the next 5 weeks so I wanted some opinions before then. They will be my 4th and 5th metrics.
Currently I try to be all prepped before a ride having eaten something and had a good drink. My Camelbak allows me to continually drink along the ride. My preferred ride food is either Musashi Growling Dog bars or some home made stuff my wife makes which she calls 'bird seed bars' made mostly of seeds, oats, honey, and peanut butter. I will have her make them into small bite sized sections so they will be easier to eat while pressing on.
I tried the idea of running on energy gels on my first big ride, and my stomach was rebelling after the 4th one so now I use them in moderation, normally only using 1 or 2 on a metric century.
As for recovery, I have a bottle of Grant's Reserve scotch which does help with the celebration feast. At my friend's house it is 'Paging Dr. J. Daniels to recovery'.

Of course, if we had a team captain I would have to call him Morgan.....
