Let...Scott, don't forget about muscle glycogen. Let's say that you workout on a Thursday around noon. Eat lunch after wards and then eat dinner that night. Your legs will accumulate glycogen based on those meals, and so will your liver. Remember, only the liver has the enzymatic machinery (glucose-6-phosphatase) to release glucose derived from the breakdown of glycogen in to the blood. That glucose can be used by organs like the brain for fuel. Muscle does not have that enzyme. Thus, if you are working out after a longish fast aka first thing in the morning without eating anything, your brain will rely on liver glycogen for fuel, which may be diminished somewhat after 12 hrs of fasting. Your leg muscles should be in pretty good shape. So its likely that these 'changes at the 45-60 min mark' are the effects of liver-derived blood glucose you are experiencing vs. actual shortage of muscle glycogen which will power your running. Also, don't forget that in someone like you, a highly trained endurance athlete, you are going to burn fat and glycogen at anything above lactate threshold, which is a lot of your workout intensities these days running 50's, etc. So you have trained your leg muscles to spare glycogen by being more efficient than Joe Blow at metabolizing fat. But really, you are only going to be using fatty acids and glycogen (glucose) as fuel sources in your muscles. Anyway, I'll stop babbling now and head to the fridge for a beer.
