I'm gonna go with Rudisha... what do you guys think?

Rudisha. Not necessarily because it would be easiest for him but because he doesn't freakin breathe.
Kiprop, because he could hold that pace the longest.
Kiprop, No question, Followed by Farah, then Rudisha.

James. The 400 is his event so it's more of a jog for him than anyone else.
Are we counting total body fatigue or just oxygen debt? David Rudisha is the least out of breath, but Asbel Kiprop has fresher legs. Mo Farah's aerobic system is the most warmed up, but his kick is muted, as is Kirani James'. Neither could run faster than 50 after that, unless they specifically trained for the 800.
Neither Farah nor James could run a 4-second negative split (with the one of the fastest second laps in known history) on their way to a 1:44.0? No sh*t!
Kiprop because he doesn't even appear out of breath after running a sub 3:50 mile.
Rudisha easy, he's a 45/46 400 metre runner with good endurance, he runs 48/49 in races all the time 54 would be a walk in the park, people go on about farah vs bolt, should be bolt vs rudisha,
James. Has the best top end speed so it is more sub maximal to him.
Honestly, who cares?
You do, otherwise you wouldn't have clicked on this thread never mind posted on it too.
This is a really interesting physiology question. Kind of related to the discussion in
http://www.sportsscientists.com/2013/08/bolt-vs-farah-at-600m-extremes-meet-who.html
I guess the question comes down to: which of these athletes utilizes the least energy from anaerobic pathways during a 54 second 400m?
If they all had equal 400m speed then the answer would be easy: Mo. But things aren't that simple. I think the way to answer it is a process of elimination. If the guys' 400m abilities are roughly (from Mo to Kirani) 48.8, 46.8 high, 45.15, and 43.94, it seems to me as though Mo's 400m best is really lacking compared to the others. Therefore, eliminate Mo. In the group of Kiprop, Rudisha, and James, we have a relatively smaller spread in 400m best. Kiprop's aerobic energy pathways are WAY better than Kirani's and probably quite a bit better than Rudisha's (Rudisha being more of a 4/8 guy than an 8/15 guy). So, easy to eliminate Kirani.
It comes down to Kiprop vs Rudisha. The question being, exactly how much better developed are Kiprop's aerobic energy pathways than Rudisha's? My guess is that it is enough to give Kiprop the advantage. Final standings:
1. Kiprop
2. Rudisha
3. Mo
4. Kirani (a distant last place)

But it's also a longer ways to run for him than for anyone else. That's why I'd say it's Kiprop. A 54 is like the first lap of a race for him. He can hold that pace for the longest so I'd say his body is most accustomed to running that pace without getting tired.
interesting question. ultimately, "least out of breath" may need to be better defined to come to a consensus on this.
what qualifies as "out of breath"? certainly if you stay totally aerobic, not using any meaningful amount of anaerobic metabolism, you are not out of breath, right? and if you have used up all of your anaerobic work capacity and faded to the point where you are at your maximum, yet can only run at a pace your aerobic metabolism can support, that would qualify as being completely "out of breath", right?
if that line of thinking is correct, my assumption is that determining the "least out of breath" would be based on some combination of who has used up the lowest percentage of their anaerobic capacity AND at what rate are they burning through it.
i don't think we can come to a valid answer without knowing their current capacities at approximately 400M through 5000M.
my gut tells me it would go like this...
1. Rudisha
2. Kiprop
3. Farah
4. James
This is a pretty interesting question and the answer would change as you change the 400m time.
Go further under 50 and it would effect James less.
Go further over 60 and it would effect Farah less.
Somewhere in the middle and Rudisha or Kiprop become more efficient in the effort.
54 is a good meeting point for the four in a one time effort after a warm-up.
They would all look like they were jogging it.
It would be cool to see this.
Kiprop; he often runs his first lap faster than that.
Your analysis is dumb.The 400 isn't particularly aerobic. The person who uses the least % of speed capacity will have the easiet time, end of story.
Why is it that "The person who uses the least % of speed capacity will have the easiet time, end of story."
Picture this: an elite miler with a 49 second 400m pr and a high school 400m runner with a 48 second 400m pr each run a 60 second 400m. Do you really think the elite miler will be breathing harder than the hs kid? While the miler was, as you stated, running at a higher % of his max speed, he was almost certainly producing a far greater % of his energy aerobically and, hence, doesn't have nearly as much of an oxygen debt (yeah, I know that term is outdated) to make up.
The question deals with weighing the balance of the speed percentage advantage of the sprinter to the aerobic energy production advantage of the distance runner. Not a clear cut answer (so my ranking could certainly be wrong...but I am 99% sure Kirani does not win).
