> Very few mere mortals could run that fast for even 100m.

That works out to roughly a 16.7-second 100m. While certainly not crawling, that would be a fairly average pace for a fairly fit middle- to early-high-schooler with a bit of practice.

Yes that’s insane to maintain for a marathon, but it’s not even remotely out of reach for 100m for most relatively-fit people at some point in their lives.

I think it's even slow for high schoolers. I didn't practice that much and ran 100m in 12.5s from rest at my peak. 4s slower is snail pace. I think most in my class could run that fast (or slow).

I think height matters for speed as a fit 6ft+ would easily run way faster than a 4" 8' fit person.

I agree. I ran mid 16s in 8th grade, and was in the 14s in high school, with the only training being whatever we did in gym class. But I do also look at the sheer number of overweight kids these days and figured, well maybe mid-16s is actually a reasonable average point.

		Oh it is. At a typical large high school making the team puts you in the top 1% or better of athletic ability compared to the population at large. At my peak, I finished the NYC Marathon in the top 2%. I still finished 45 minutes behind the winner. It feels like elite athletes aren’t even competing in the same sport.

It's the "at some point in their lives" that matters here. For most folks, the period where a 16.7 100m is feasible is pretty short.
