This is DEFINITELY not a great idea without pre-clearance from a doctor, and even then it's not great for you. I would imagine this places undue stress on many body systems. Your muscles (and brain!) really really want glucose when you're working this hard. AND he was at altitude. Ketosis workouts DO work very well though. I just don't recommend an Ultra while fasting... |
