So he won't get the record after all? Just top 5 or top 10? I thought so.
So if it is just "endurance" that is required to beat the record, and speed is irrelevant, how is it that no great endurance runner has got near it in 25 years?
You show you have no understanding of the reality of running, that with each distance from the sprints up there is a progressive slowing, and that a given level of performance requires speed as well as endurance. As a 2 minute half miler cannot run a 4 minute mile, a runner who cannot run substantially faster than 3.40 for the 1500 will not run 7.20 for the 3k. An athlete must slow as the distance of the event increases - the splits cannot be anywhere near his best over the distance they measure. As the 5k world record holder Komen showed that sub-3.30 speed over 1500 was necessary to run 7.20 - and he had phenomenal endurance. No one slower than him has got near his record. They would have no chance. That is also Cheptegei.
No one faster than Komen got near his record either.
I wouldn't dismiss a WR completely -- his 5000m WR predicts 7:12-7:16, and his 10000m WR predicts 7:11-7:14.
It will largely depend on pacing, drafting, and how fit he is now, in mid-May.
7:23-7:25 is just a conservative prediction that would still be a huge success towards the goal of the Olympics.
I didn't say speed was irrelevant. I said you don't need 3:29 speed, as you claim is necesary. You need 3:40 endurance. With stronger endurance, like Cheptegei's, you would need less speed.
I have already explained why great runners didn't get near it. The greatest ones didn't really try, because 3000m is not an interesting distance to train for. It is not an Olympic event, nor a World Championship event, nor really a Diamond League event. However, it was run in some of the early years of the Golden League, and in some Diamond League races.
Your model of progressive slowing for longer distances only makes sense when we have maximum efforts to compare. In a modern training context, we do not always have maximum efforts, but constrain our SPECIFIC paces to 95%-105% of target race pace of the desired event.
