Anyone know who the youngest sub-4:00 miler in history is? 16 yo Jakob Ingebrigtsen is trying to do it at Pre

Big deal. Wake me up when he runs the equivalent of 1:41 800m at age 18 like GOAT Nijel Amos.

And never ran faster. Probably collecting his pension now

He might as well be retired. It would at least save him some grief and frustration- meaning, he is now training with otc.

All western cultures respect numbers like 1, 2, 4, 5, 10, 25. I agree. Just do the 1600.

Sure it would, as long as the first 391 meters was not faster than 55. Then you'd have the middle 1218 meters no slower than 4:02, followed by a 57. Who opens a 2000 in 55?

It's difficult but not impossible to run a race greater than 1 mile but less than 2 miles at an overall sub 4 pace without running an actual sub 4 along some mile subinterval of the distance. At 2 miles it is impossible, after 3 miles it's again possible. I think I posted a proof of this some time back.

yeah, the question didn't say "official finish time" or "official split" I think.

Didn't Kipchirchir run 3.36 at 17 back in about 2004

Exactly. Why no one wants to know how fast anyone can run 1600 or 3200m. 1 mile and two mile on the other hand.....

Does anyone know who the youngest person was to break 3:48 for the 1500?

Jakob Ingebrigtsen ran 3:48.37 at age 14. And 3:42 the year after.

This seems correct, but I'm not sure what you mean by at 2 miles and after 3 miles? The proof is basically trivial. In the case of an n-mile race, if miles 1,2,...,n are all over 4-minute pace then you've got a contradiction. In the case of an n.x mile race, then either the n-mile race from 0 to n or 0.x to n.x is sub-4 pace and just use the same proof.

Actually that last part isn't quite right - can you give a counter example of a 2.x mile race that violates this? 0.75 miles really slow, 0.6 miles fast, 0.75 miles really slow? What paces? After 3 miles it's easy to show.

I found them. He split 3:56.5 at the one mile point.

Post a link or it's total BS. You easily (and probably) could have just made that up.

Let's abolish the Marathon while we're at it and replace it with the 46k run.

16 is not in your list of respected numbers.

Ingebrigsten probably could have broken 4 last year if he actually ran a mile race, given the 3:42. I'm more than confident that he'll be under 4, and could even take some scalps. It'd also be great if he did so that people would stop talking about Jim Ryun already.

The marathon was 40k until the queen of England decided the event had to end at her royal box. True story.

This is an interesting problem has is more complicated than I expected:

It's rather surprising that the average-pace must have a subinterval at that pace ONLY if the race is an integer multiple of the subinterval.

All African claims have an asterisk. I discount them.

so a kid from Norway can break 4 but a kenyan cant? lol

Didn't say no under-17 African could do it. The asterisk is because one of the variables (age) is pretty much unknowable, and there is incentive to lie.

Norway's Jakob Ingebrigtsen, kind of looks like

Magnus Carlsen's brother.
