The fastest marathoners are moving at 4m30sec per mile or faster.
Very few mere mortals could run that fast for even 100m.
There's an interesting video by Mark Lewis on this.
Here's a random high school in Northern California. Everyone on the team is beating 16.7 seconds in the 100m. For the 1600m there are six kids with times under 4m30s and another seven with times under 4m40s, all in the last month.

* of course one mile is hardly comparable to the marathon that pros are able to sustain such speeds over...
Sometimes they have big running machines with a crash mat around them running at 2h marathon pace at running shows. I’ve o ly seen them on video - no one can keep up with it for more than 30 odd seconds. It’s INSANE they are running this fast.
Also bear in mind running a single mile under 4 mins was considered impossible for a long time.
We used to be amazed when I ran cross country in high school that these pro marathoners would best all of us in our approx 5K(3ish mile) races and then go on to repeat that distance multiple times.
It’s totally remarkable.

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.
