kratochvilova was still an amazingly talented athlete.she ran a 51.08 in 1978,and a 1.57.6 800 in 1987,probably clean.way slower than her 47.99/1.53 world records,but lots of drugs alone couldnt account for her world records.she must have had great talent,in the first place.as it is,im not so sure juantorena was clean.

Agreed.
Somehow, someway, he moves every thread he pollutes, away from the subject of the OP and into a Broadcast for Jim Ryun.
He should be ignored because most of what he writes is embarrassingly so far from any reality that it's not even worth questioning or arguing with.
Never sticks to facts, which are....
Ryun ran 880 WR on synthetic track.
It was hand timed and thus would have been slower using automatic timing.
He never broke the 800m world record because there was no official timekeeping for that point.
He only broke 47 secs once for 400 or 440, in a relay, with hand timed 46.9, despite running dozens of relay legs during his career. There is no video of this race to check, except about 15 secs of the race at the wrong speed and hardly visible, at beginning and end of the race. About 3 secs of bend running can be seen so it is impossible to claim he ran very wide.
Ryun broke 1:45 once and 1:46 twice. To claim he could run 1:39 with that sort of evidence is embarrassingly laughable.
Ryun ran in 3 Olympics, had the opportunity to enter 5 events if he chose to take on 2 distances at the US trials, and came away with a single silver medal.
These are facts. Not far fetched nonsense that Calculo offers.

He's not though.
400m a sprint 800m middle distance.

That being said, there are a few guys out there who I'd consider world class at both. I imagine 2012 Rudisha could run low 44s for a quarter. 2015 Bosse and Tuka were probably sub 45 in peak shape. Amos split sub 45 on at least one occasion.
You're being far too generous there.
2012 Rudisha ran 45.5 v. early in season. By London OG I'd expect him to run 44 high.
Bosse & Tuka have never shown sub 45 open ability. I'd give Tuka 45 high/46 flat and Bosse 46 low-mid.
Amos split a 44 something, so I'd expect him to have been capable of a 45 flat/low in peak condition for an open 400.

Physiological demands are far more similar between the 1500 and 5k than the 400 and 800.
There isn't a totally set consensus on the number (and I'll probably get torn apart by a few other posters for this), but 400 --> 800 is generally considered a shift from about 10% aerobic/90% anaerobic to 50% aerobic/50% anaerobic. 1500 is closer to 90% aerobic, with 5k slightly higher.

I would say your estimation on the 400 is off. The first paper below uses a mathematical model for hurdling. (There looks to be serious math to a person with only 2 terms of college calculus!).
The second paper is a little less "math-y".
The 400 is more aerobic than most people think. (Not to call it an "aerobic" event, just that oxidative energy systems contribute more than most people think).
