6.2m/s or 22km/h (20ft/s or 13.8mph). The average human can definitely sprint faster than that, but obviously can't keep up that speed for long.
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.
16 > 13.8 no?
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.
For an additional reference: the 100m Olympic times are ~10s, so if you'd run at a sprinter pace it'd be 1:40/km. Marathon times are insane.
