The fastest marathoners are moving at 4m30sec per mile or faster.

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.

The fastest 1km I ever ran was around 3m20s, I felt like I was sprinting, and was fully cooked at the finish line.

Afterwards I did some quick numbers and realised the average marathon runner was not only going a lot quicker than I was, but they were doing it for a further 41km

  • You've proven you can run one kilometer. You just need to prove that if you run any km, you could run the next km, then you're done.

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.
