Zach Bitter interesting. I think he perfectly demonstrates the point. His world records were for the 100mile and 12hr on the
TRACK. The physiological requirements for this event, never would exceed 60% of VO2 max. Interesting that he has no result in the events that ultra trail runners count. Hardrock, Western States, UTMB. So why would a world record holder never feature in any of these events? Perhaps as soon as he hits a climb, and the intensity increases, he blows up?
But exactly how low carb is Mr Bitter?
“
I think it’s beneficial to start out strict to those parameters [50g per day]
and let your body adapt but then once you get back into the flow of training, I think 100-150 grams per day carb is probably a better starting point”.
So half of this everyday?
