I only did one but found that around 21-22 I could feel my energy going down and it just got worse and worse, but my overall speed did not decrease, it was just more and more difficult to keep up the speed. I saw LOT of people walking those last few miles, though. I don't think it was a body limitation for them so much as just inadequate training or weight or on-the-run fueling.
That's "The Wall" I was talking about. It's when a person's glycogen store runs out, and energy must start coming from fat. It happens at ~20 miles.
