When will Ethiopians understand that you don't beat 1500 runners in a 13:15 min race ?

Rounds in the 800 take their toll on runners too which is why the times are often fairly slow. The distance races this year were incredibly slow compared to other world championships. I wasn't there so I don't know how the weather effected them but I remember 1999 when the weather in Seville was often 100+ Fahrenheit albeit a dry heat and the times were quick.

I don't think the heat is a big factor, running hard is running hard, the only difference is the time when its hot. As long as you are acclimitised, you push the pace by effort and not time then. They went out in 8:11 for 3k which is a jog no matter what the conditions are.

And also, 6 men broke 12:50 in Monaco last month when the temps were in the 80's. All the Ethiopians demolished Katir in that race but he walked away from them last night precisely because they just jogged.

The reason they don't push the pace is simple, they are Ethiopians and they never do, its not in their nature(bar Bekele 08 and Haile 03). I cant be certain but I'm sure it must be something that is drilled into them since youth because it's a defining characteristic of Ethiopians in Championship races.

Kipkirui who you noted is not near the level of the rest of the guys in that field and it wasn't that the heat killed him, he's just not a good enough 5000 runner... yet although his future is probably 10k/roads. He was also trying to do it alone, the Ethiopians could have made a concerted effort to do it and actually test Jakob and Katir

Katir demolished them too in Florence with a 12 mins 52 secs paces.

But I do believe that Jakob/Katir had zero chances to medal yesterday if the pace was around 12 min 45 secs.

It’s not a DL race.

Same reason Jakob lost 1500m even with WL

I totally agree with this. If you front-run 12:40 during the season but don't even attempt to recreate that strategy when it matters most, I'm not sure what you expect to happen against 3:27/28 1500 guys. Same thing as when Mo Farah was in his prime; the others ALWAYS let the race play right into his hands every time. I hope the 12:40 boys will learn from this, they weren't even close to Jakob and Mo in the last 100m...it was basically a mile race and the milers dominated.

Kejelcha et Gebrhiwet both ran 12:45/46 wild old spikes if i'm correct

I tend to agree too, but I remember the Sydney Olympics 5k won in 13:35.49 by Million Wolde of Ethiopia (3:39 1500m PR) over Ali Saidi-Sief of Algeria (3:29 1500m PR). Everyone expected Sief to win. He went to the lead with 2 laps to go but Wolde got up to his shoulder on the final lap and passed him on the home straight. So, if you knew Ingebritsen was sick, and that Katir had performed poorly in the 5k, and you watched film from Sydney the night before, maybe you thought you could handle those guys on the last lap.

Same in the womens 5k, basically handed it to Faith Kipyegon

In 2003 its Kenenisa Bekele that paced the race. The TV presenter here even speak of WR pace by Bekele. But I think we are far from this generation of runners.

Listen to the critic here. Having been in some fairly big races myself I can tell you that having the balls to take a championship race out hard is rare. The Kenyan tried to run away but he didn’t seem to have the ability to sustain. Do you think the Ethiopians should have gone with him? It would have been more interesting but I am not sure the result would have been better for them. We just don’t know.

Kipkirui, I'm not sure what the gameplan was. First time out there, probably just didn't love all the jockeying in the pack. But I do think Aregawi not drafting off of him was a mistake. Not because he thought he'd sustain it but because a 13-flat race was a much better chance of a medal for him. He there had an opportunity to get a few fast laps and a jump on the field without having to do it all by himself. Running in the pack clearly doesn't work for him in a slow race.

At some point, the Ethiopians will have to realize that the following guys are going to beat them like a drum if they don't make it an honest, fast race from 1600 or 2000 out regardless of how hot it is:
-Jakob
-Katir
-Grijalva
-Krop.
The latter two screwed up their positioning and still got them. Nur might enter this group soon enough. Kiplimo and Cheptegei if healthy get the edge as well.
Their other option is to find a way to get Barega in because he is more competitive in the kick if he is peaked properly.

Well I wonder if we are seeing the torch being passed soon in Ethiopia, but to whom precisely I am not sure. It seems that prime Edris would have done OK yesterday, but he is past his prime and despite stellar 5000m race this year, one wonders how much Gebrhiwet, Kejelcha and Barega have in the tank, despite the latter two being not old at all, at least on paper. Maybe the younger Girma or some others will emerge, and it is not as if Ethiopians cannot finish fast. Certainly prime Kenenisa and Geb would have done well yesterday, although as you allude to, they probably would have wound it up with 1600 to go and maybe broken Katir and Jakob. I think the Ethiopians need a new generation to defeat Jakob at 5000m. The young Kenyan is one to watch apparently.

So he sacrifices himself to keep Jakob and himself out of the medals?

The only answer against the fast kickers is for them to have agreed to push the pace together, taking turns.. really hard to do but they could have pulled off a sub 12:50 like that.

Thats the same reason because Jakob lost two gold in 1500 from Wightman and Kerr. With a big difference . Jakob has 5000 WR in his legs and near to 10000 and then Half marathon just wait and see

WC format had very little to do with their tactics. They ran 13:30's in the heats to advance to the final and had at least 2 days rest. A 12:50 pace from 12:40 men would have been difficult but it would HAVE been the best tactic against Jacob and Katir.

That's why I'm beginning to believe the IAAF or someone is paying athletes to hand the race over to Jacob. Just like the Kenyans and Ethiopians did for Mo Farah.

This is an IQ issue though. VIPAM you are inclined to believe all kinds of nonsense. So they paid the 5000m field to lose but not the 1500m field?

Crazy conspiracy talk aside, anyone who does not believe Jakob is (at least) a 12:40 guy is completely ignorant. Yes, he had a virus, but nobody knew before the race what impact, if any that would have on him.

The last thing the powers that be want is a white guy winning anything.
