It's about as basic a nutrition/metabolism issue as there is, and yet threads like these still pop up because people buy into these ridiculous premises that are either completely fabricated or heavily misleading.
The guy was still adapted to burning carbohydrates, rather than fat. If he was properly in ketosis he could have done a hard effort burning fat. If--and the big thing here is that if--you are properly in ketosis, you can go as hard as you like, provided you take on sufficient fat to power the effort.

Ketosisis in no way a ridiculous premise, it's merely the body adapting itself to utilize fat, rather than carbohydrates, for energy. I know someone who rode a couple of 200K brevets drinking from a bottle of olive oil, just to prove that it could be done, to himself as much as anyone.

You just need pee strips to verify the presence of ketone bodies in your urine and the discipline not to cheat and eat a donut, because you'll be dragged straight out of ketosis if you do.

Carbs are a much easier way to fuel efforts, but they not essential at all, provided you are properly in ketosis and consuming enough fat to provide you with energy or have fat stores you can draw on.
