3. Consume approx. 200-300 calories per hour on rides over 2 hours. Plus one 750 ml bottle of water and/or sports drink every 1 to 1.5 hours during the duration of the ride.
Actually a good way to extend endurance is to do the exact opposite. Ride without any calories as much as possible. No sports drink, no PBJ, no peanut butter cookies unless you absolutely have to.
You have a certain amount of energy (glycogen) stored in the quads. When you ride, you burn some combination of muscle glycogen, fat and on-the-bike carbs. If you're just starting after a long break, your stores are low and you end up running out quickly. Long glycogen-depleting rides without calories encourage your muscles to store more glycogen and to use more fat. It is totally possible to go 60 miles at a brisk pace without any food (though maybe not in time-trial mode).
0 to 22 to 44 is a recipe for burnout, if not injury.
If the OP manages to injure himself by going 0 to 22 to 44 miles (and by "injure" I don't mean irritated rump), and he's less than 80 years old and otherwise healthy, this will probably be the first case in history. (Unlike, say, going 0 to 5 to 10 miles in running, which would easily lead to an injury.)
