Except then you would still eat carbs the night before a race because not having glycogen is just intentionally gimping yourself for no imaginable possible gain. It's not like the mj of glycogen energy is weighing you down. You should absolutely train in a glycogen depleted state just so you will know what it feels like and can deal with it. But it's not how you would ever start a race.
