Should I eat breakfast before or after morning ride? I am planning to do some (1-2 hours) base training rides in the morning before work. Should I eat something before the ride?

From my knowledge, there should be enough glycogen in muscles to power me. Are there any other considerations? What if I increased load to strength and interval training?
I think that is question can at least be partially answered by whether or not you can tolerate food in your stomach.  While having a big heavy meal would probably be bad, having something in there, plus doing some refueling along the ride will help you keep from bonking and also make sure you are not running on a deficit for the rest of your day.

I find that if I have a light breakfast and then add to that energy gels about every 45 minutes I am pretty good.  My riding buddy, on the other hand, eats a McDonalds McMuffin and hash browns which would make an explosive exit if they were in my stomach.
