The answer is obviously Rudisha. The man averaged 50.45 in his 800 WR.
Can you run repeat 400s at half a second faster than 800 pr? Of course you can. Take 10 minutes between reps and this will feel very manageable and you’re done in 2 hours.
Thank you for offering a bit of intelligence here. This was my first thought upon reading the title. How many sub 50 could he do with 5 mins rest? A lot.
Well obviously only an elite 800m runner is likely to be able do it, perhaps a 400m runner but most are lazy sprinters, who is really only good for 300m. I don't think anyone could do it but it is a running start? Or is it from blocks?
Alan Webb could have.
Probably someone like Kiprop if you could make him put any effort into anything.
He has decent endurance, decent speed-endurance (1:43), can certainly run 46/47 for 400m.
Farah also probably has a chance because he has closed 5ks in 50.x my concern would be that he probably can't run much faster than 48/49 so it's cutting it fine.

But the evidence we have from training sessions shows that Geb and Morceli did faster 400m sessions than Webb.
I didn't say only Alan Webb. Add Morceli. Makh Daddy for sure too. Many others could or can do it.
Geb was an endurance monster, and had only a 49.9 open 400 best, so no.
We don’t need names. 45 second runners could do 6x400 in 49 at 6pm and repeat it at 4 pm the next day. Give them 6 minutes rest and they would be fine.

That wouldn't work. For one, even if they could do what you say, they would only get in 6 in 12 hours.
I’ve known a few elite 400 runners, sub 45, including those that raced CC in HS.
They were incredibly specialized for running the 400 and would run workouts that a 1:58 guy could handle.
I think Letsrun is too distance centric to realize that a 400m guy is not the best pick, 400 runners have very little base, perhaps not even Rudisha.
A 49 is just not fast, I know a lot of you think it is. Mahkloufi, Webb, Souleman, those types are the guys for the job. They could probably run a 49, jog for 10 minutes and blast another one, rinse and repeat and get 6-10 of them done in the first hour and a half.
umm have you heard of Alysson Felix? wrote:

Felix's PR is a low 49. How could you realistically expect her to do that 12 times in 12 hours?
pretty easy.
I used to run 49s with a couple of minutes between. I could take longer and peel of 6 in the morning, have a few beers and do 6 in the afternoon. Rinse and repeat next day.
I ran 46. And the seconds above that are like dog seconds. 49 for me was like a 1:50 guy running 2:05.

The point about "dog seconds" is spot on. You use A LOT of extra effort to squeeze out those last couple seconds in a 400. I wasn't this fast, but I know I could have run 12 52s over the course of 12 hours, so I have no doubt that an 800 guy who could run 46, or a 1500 guy who could run 47, could knock out a dozen under 50.
I screwed that up. They can do the first set at 8am and the next set at 6pm. No problem. I have seen high school guys run an open 400 in 48, another in the sprint med, and finish the 4x4 all in 3 hours when their PRs were only 48.
I could :D
Oh... you said 400s, not 200s. Maybe not D:
Any good 400m runner given the inventive.
Say 46 or faster
Centro
Seb Coe easily. His top speed was pretty phenomenal - 46ish 400 , 10.7 100m

Why did this have to come off as condescending when you basically said the exact same thing as several others on this thread?
Makhloufi goes nuts in this session...
800m in 1:44.5s
10min rest
500m in 64.5s
4min rest
400m in 52.5s
2min rest
300m in 39s
Seems like he could run a bit faster than his 800m pace for 400m twelve times if he hydrated and ate well.
This is easy - MJ - the greatest doper in history in 6 hours most likely.
