My early morning rides are before work and limited to 1-1.5 hours so I don't have anything to eat. A small glass of OJ is all.
For longer rides on the weekends, Oatmeal with a dozen or so almonds, whatever fruit I have available, some unsweetened coconut, and a bit of maple syrup or brown sugar. That will hold me for at least 50 miles.
I've discovered that at 64, I cannot eat eggs before a ride of any significant distance.
