I didn't know the OP was only doing a 15 minute ride. I was more imagining that they are riding with a group on a 1 or 2 hour ride. And the other group members are capable of doing that ride solo at a 18 mph average.
That'll drain the energy out of the best of noobs whether it's entirely glycogen or not. And the OP did claim to be tired for days afterwards.
But in no way was I asserting that glycogen depletion was the entire reason for their problem. Perhaps I should have just said running out of energy.
