Jakob in the 1000m

I would not agree with you, Lamecha Girma is as tall as Jakob, with a similar shape, I don't think Jakob is a rhythm runner, on the contrary he changes his rhythm easily, seeing all his 5000m, and he has enough experience with steeplechase. I think he can legitimately attack WR.

Jakob ran an 8:26 steeple at 16. I would bet that he can run sub-8 now and probably the world record. Girma is almost as fast at 3k flat, so it wouldn't be easy.

I think that Jakob would run 2:13-2:14, but I don't see him cracking 2:13 before running 3:42 in the mile/3:25 in the 1500m.

Jakob not only beat the mid 1:43 runner Habz and the mid 1:44 runner and clear winner of the UK 1500m trials Gourley in the Euros he DESTROYED them completely with an obviously faster top speed (Habz and Gourley were already starting to be gapped before the 1300m mark where they both were all in when Jakob was still cruising. And when Jakob shifted gear around 100m out they had nothing left).

If Jakob joins a fast 800m race under good conditions and in top shape he just has to stay behind at the rail until the 500m mark and then go for it from there. He will at least be able to run 1:44.5 as Salvatore states.

Nothing indicates that he is slower than Kerr. And he is certainly faster than the Kerr we saw at the UK trials.

Feel like you're on to something. While some people say JI is a 1:46 guy, I do not see him going slower than 1:44 peaked in a good race.

He ran 3:27.14, what means 1:50.x 800 and then another 700 at that pace. Without at least 1:44 capability this is not possible imo. I see JI roughly at 1:44.0 +/- 0.5" when he ran that 3:27.14. Therefore he is able to run ~2:13.0 for 1k, what makes perfect sense. Wightman ran 1:43.x and 2:13. Wightman might be a bit quicker than JI in a 400, a bit quicker or equal in the 800, a bit slower or equal in a 1k and much slower (2+ seconds) in a 1500.

Wrong. Jakob would get destroyed by Habz and Gourley in the 800m. 1500m / 3000m / 5000m runners are not (and do not have to be) fast in the 800m. As a matter of fact, this is the reason why Jakob runs 3k and 5k. It's because he is just not that fast in the 800m. 1:45 flat is the best he can do, IF he trains specifically for it. Otherwise 1:46 at the moment. What Hobbs, Habz and others run have nothing to do with Jakob, who has a completely different running form and training regimen.

To prove it even further, that 800m and 1500m times do not have to correlate, we can take a look at Josh Kerr. He is going to demolish his 1500m PB despite getting slower in the 800m compared to his previous seasons.

Everything indicates he is slower than Kerr. Including his race strategy. If Jakob was a 1:44 dude he would wait a long to take the lead in championship races.

There's no way Jakob wouldn't be able to run at least 1:45 in the 800 right now, most likely 1:44. Tons of runners with much, much slower PBs in the 1500 who can run a 1:45 in their sleep.

I took a look at Jakob's splits from his 1500m in Silesia last year. (3:27.14)

His first 1000m was 2:19.3 (Followed by a last 500m of 1:07.8)

His last 1000m was 2:17.3 (after a first 500m of 1:09.8)

I think it's reasonable to say that he is capable of 2:13.xx

He could definitely crush the Norwegian record, which is 2:16.46 by Filip in 2020. (The former Norwegian record was 2:16.78 by Vebjørn Rodal, 11 days after his Olympic gold in Atlanta at 1:42.58. (According to Rodal he ran his 1000m race a day after a bachelor's party to a friend))

(El G's world record of 3:26.00 is the equivalent of running a 1000m in 2:17.33 and the continue for another 500m in the exact same pace)

Another follow-up question is what could a prime David Rudisha and a prime Wilson Kipketer have done in the 1000m?

(Kipketer's indoor PB is 2:14.96 (2000), which was the world record at the time, while is outdoor record is 2:16.29 (1995))

I respect Jakob a lot so i’m never going to say he is incapable of running anything. That being said Jake wightman ran 3:29/1:43 and then runs 2:13.8 at Monaco over 1000m that same year. The thing with 1000s are they are very very difficult to run, if runs like an 800 he risks potentially closing too slow but he may start like a 1500m and finish the race feeling like he didn’t run quite hard enough. For sure it would be interesting but my guess would be around 2:14.0. I also would not be shocked if he ran 2:13.0.

If Ingebrigtsen has better top-end than Kerr, Kerr is be capable of sub-12:40.

“…stay behind at the rail until the 500m mark and then go for it from there.”

Stitchmo‘s blueprint thread, has triggered absurdly precise descriptions of proper pacing for the 800m.

Under ideal conditions Jakob could break the mile WR but breaking 3:26 flat or 3:42 won't happen since he has not even broken 3:27 and he would have done it by now. He should focus on 3 K or perhaps 5 K WR --the latter also extremely hard for him.

This is correct. Both Steve Scott and John Walker, ran about 1:45 and were also strength runners. Walker ran 3:32, and Scott, a mile conversion of 3:30.7.

Yup, and Andreas Almgren who started out as an 800 specialist and has been gradually moved up the distances has PBs of 1:45 and 3:32

I think the real question is what Jeremy Wariner would run in an 800

Jakob is a 12:40-12:45 5k runner. Steve Scott wouldn’t be with 250m of that.

Why do you think Jakob is 12:40-12:45 runner?

I don´t no why Jakob having better top end speed than Kerr (which I DIDN´T state) should make Kerr a sub 12:40 runner.

No my 800m advice is tailormade for Jakob who´s only weakness is his acceleration from scratch and high pace early in the race. I was an 800m runner myself and ran completely differently since my acceleration and speed was my strongest card (I always tried to get the first position behind the frontrunner).
