Letesenbet Gidey runs 44:20 15k, SMASHES WR. Equivalent to a 13:42 5000!

Ops...... Obiri won in London diamond league in 14'20" not Hassan as I said before

Yes, i just checked that myself. It is the best performance in the history of women's athletics.

We will have to wait for 2020 and see if she has some sort of continuity of this shape. If yes, i'm already sorry for all the other athletes, they will get crushed.

Even in the 3,000m, in this shape, Gidey can run at least 8:10, so if she takes it up early, Hassan will be in big trouble. As for 5,000m+ it's Gidey's race to lose, regardless of who else does compete.

In addition, we have seen significant benefit from the new shoes. Again for the marathon, the effect has been estimated at 60-90 seconds, or 20-30 seconds for 15K and 15-22 seconds for 10K.

Those benefit ranges are way too narrow. Going back to my previous post on the CU Boulder study, the efficiency benefit ranged from 1.59% to 6.26% for the Vaporfly 4% (on already fast, sub 31 10K runners), so a four times difference between the lowest benefit compared to the highest Vaporfly responders. Another way to look at it is that the highest responders to the Vaporfly gained 50% more than the average responder.

The efficiency improvement numbers for the Next% were not released to the public, but they did say that people were testing above and below 5% gain. It's reasonable to assume a similar 4x spread between lower and highest Vaporfly Next% responders, so there are likely 7%+ responders in the Next%.

Translating from efficiency gain percentage to speed gain (time loss) percentage, maybe reduce the percentage a bit? The NY Times study showed 3-4% time loss between similar runners without and with Vaporfly 4%s.

With the hugely variable gains that different people are getting from the Vaporflies, you can no longer do that kind of comparison.

= 8:01 for 3000m per IAAF

Then we should erase all records because of technological advance, give me a break. As for the 3000m, i think Gidey is stronger as events get longer, so i don't think it's accurate to translate this performance to a lot shorter, track one.

Why hasn't letsrun covered her race? It's arguably one of the most remarkable long distance running performances of all time.

Because then they'd have to admit that this extremely beautiful lady is not only faster than the site founders but is gorgeous as well. In general men hate being one-upped by a woman in an athletic event but make it a beautiful woman and the hate is 10 times stronger...

What's with your obsession with her looks? You seem to have mentioned it in the majority of your posts. That's weird, dude.

El K is a certainly a creeper.

It’s called doping only if you are caught, otherwise it’s just pushing the frontiers of nutrition and science. We have no reason to think that Gidey takes performance enhancing drugs below the detection threshold any more than most elite runners. If there were a magic invisible super-drug, it’s unlikely to remain available only to (relatively) poor East African countries, so it’s an equal opportunity sport.

Going by how often Gidey seems to have exercise-induced nausea, one could speculate that she takes something just before the race that gets “used up” during the race down to near-undetectable levels and puking out the rest clears out all evidence, but it’s just that — pure speculation — because if this tactic worked, others would employ it too and it would soon likely become unusable anyway as the anti-doping agencies get smarter; they really aren’t stupid and have a huge huge incentive to keep the perception of clean sport intact.

As for arguments about how she could run the last 10K of a 15K at WR speed or significantly faster than her PB a couple months back, they are hardly conclusive. Distance running has always been somewhat counter-intuitive: runners sometimes fall and still win the race, but it’s entirely possible that if they didn’t fall, they may not have won. With pacers, you can stop to pick up a dropped drink or deviate from the shortest blue running line and yet not lose any time at all. Hills are usually harder but it’s possible for a net-zero elevation to feel easier for some runners’ bodies compared to others. Genzebe Dibaba ran 1500m in 3:50 and you’d think she could have run 109m more meters in 20s breaking the WR but her best mile time is 4:14 something and Hassan holds the mile record at 4:12 something.

The simplest explanation for this 15K is probably that Gidey pushed herself to near breaking point and that is what made her sick right after. Gidey is also different from other comparable runners (like either of the Dibabas, Hassan etc.) in that she has no final kick and seems utterly incapable of increasing her pace beyond her calm pace but her calm pace is already pretty aggressive and maybe she has just figured out how to maintain it for ever increasing distances.

It's doping whether you get caught or not. Generations of athletes have doped without being caught despite testing and things like biological passports. Just a few years ago there was another major doping scandal in cycling which showed how easy it was to beat the controls and shed light on the tactics used. The small percentage caught compared to the number of athletes who admitted doping is remarkable. But delude yourself however you care to.

Stunning performance at Dutch Zevenheuvelenloop

Editor's note on 11/20/2019: The thread was initially titled "Letesenbet Gidey under 44.41 15k!" but we changed it to better reflect the monumentalness of her accomplishment. According to the IAAF scoring tables, the mark is equivalent to a 10.46 100, a 1:51.53 800, a 3:46.25 1500, a 4:03.51 in the mile, an 8:31.51 steeple, a 13:42.33 5000, a 28:44.31 10,000, a 1:03:07 half marathon and a 2:11:51 marathon.

But, was it done in lingerie or no?
