Half marathons are right at the very limit of depleting your liver glycogen stores(100-200g). Anything beyond that, you better be eating quick carbs during your exercise, or you will start burning fat.

Well yes, that's why I picked that distance :) For a good performance, you want to be replenishing continuously anyway.

And you are always burning fat. Human minds like to break it up into nice progressive steps or state machines but the actual body is just a highly parallel beast. Just that as you get closer to VO2max, the proportion shifts dramatically in favor to glycogen over fat.

I am not sure that's true, most marathoners (incl. myself) would report "hitting the wall" at around 20 miles.
