Vo2 max, efficiency and lactate threshold...I think I once read that in testing Kipchoge had freakish LT, that his body hardly produced any lactic acid at allWhat are the physiological impediments that stop a man running 13 mph plus for 2 hours?
The one thing that struck me most about yesterday, and I watched it in full, is just how effortless it all looked. He never wavered from the target pace, he sprinted the last km in 2mins 40, then was running around the finish areas for minutes afterwards celebrating before giving his interviews seemingly fresh as a daisy...sure that could have been adrenaline after what he’d achieved, but it was startling, none of the usual collapse we often see at the finish line of the marathon, no outward indication that he’d just pushed himself to his absolute limits.
Compare all of that to the Monza attempt
I’m convinced he could have gone even quicker than he did yesterday by a significant margin
