When I was running marathons and in good shape, I tried to reach Kipchoge's marathon pace on 100m. I did not reach it by a tiny margin. I disliked and never trained for short distanced and that was a single attempt for fun after 5K jogging, which was more a warm-up than a load. My shape was definitely above "the average human" at that time. Their speed is incomprehensible.

the average human certainly can not run that fast. treadmills in gyms usually cap at 20km/h and how many people on the street do you think could handle it? (very few of course)

Adjust for weight : he is 5’9”, 123 lbs. he is 60% the weight of an average man.

I’m in fairly good shape from biking pretty much every day and my average _cycling_ speed on my hybrid bike is below that, my goodness. If I’m on a completely flat trail, carrying nothing else with me, and I’m really pushing it I can average about 16 mph for an hour but to know that there’s someone out there running as fast as I bike is absurd.
