Eliud Kipchoge Breaks Two-Hour Marathon Barrier

Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#162So Kipchoge had rotating teams of pacemakers running _before_ him, throughout the race. Each team was able to outrun Kipchoge for a short amount of time, but of course Kipchoge himself had to keep the same pace throughout the race. This reminded me of an episode from Terry Pratchett's Small Gods . This is mostly from memory, but he describes an invasion of the country Ephebe where the invasion force comes from the si…
I don't know for sure but I strongly suspect that Pratchett was heavily influenced by Operation Black Buck: https://en.wikipedia.org/wiki/Operation_Black_Buck In particular, this diagram from that page makes the process clear: https://en.wikipedia.org/wiki/Operation_Black_Buck#/media/Fi... Hopefully the name of the original mission is enough to help you find a link to some relevant mathematics :-)
This blog post has a great detailed description of Operation Black Buck: https://www.navalgazing.net/Falklands-Part-6

#163Count it! Cuz in everyone's mind, we do! We don't care about the technicalities, we care what a human was capable of doing. The crowd was a huge help in getting him there. Nike's course was sterile, this one specifically had crowds to help.
Nobody denies that this is a tremendous achievement, but there are rules to world records which have to apply to everyone, if they apply at all.
I'm sure even people at IAAF who decided not to accept this as an official record are happy for Eliud. But the rules are the rules.
In my mind, it's not detracting from what Eliud has achieved in the slightest.

Marathon runners would run naked if they could. Certainly don’t want or need some heavy gadget on their head.
A device like google glass wouldn't be much heavier than their usual glasses.
There are specific limits on the size and functionality of sunglasses at sanctioned track and field events.
Some events don't even allow the use of Garmin watches (by elite runners) because they can be used for pacing.
Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#165That's running 42km at 21km/h… Anybody who already tried to run a sub20 5km (5km at 15km/h) knows how crazy this is.
Exactly, I was a middle distance runner back in high school and nowadays focus on half and full marathons. I'm far from being an elite runner, but I do alright at local events. I can barely keep Kipchoge's pace for 1km.
It’s crazy that he runs 1km under 2:50s, and he does it 42 times straight!

Congratulations on qualifying for Boston. I found "Jack Daniel's Running Formula" an invaluable resource in learning how to obtain the best performance from your body. His V-Dot fitness estimator can predict your marathon time (with optimal training) from your 5k race performance. I also had a goal to run a 3 hour marathon, but my 5k race time was just a few seconds too slow to extrapolate a 3 hour marathon. I did hi…
Thanks. Sorry to hear you've written off sub-3. I've got that book and many others. :-) I got myself from a first marathon of 4:22 to a 3:36 with Pfitzinger and stubbornness, to a 3:22 with Crossfit, improved running form, and more training, and to a 3:12 BQ and then 3:07 PR with better training. I respond well to mileage, but need the strength training so I can put in higher mileage without injury. Knocking off anot…
I agree that longer runs are better predictors than 5k's. I was limited to about 45 miles over 4 days per week to avoid injury, so you may be in a better position. The marathon is a multidimensional challenge, so there are lots of levers to play with. Good luck.

#167I can't sprint that fast nowadays. When I was in the Marines 20 years ago, my 3-mile pace was slower than that, and I still had a class "A" run time. This is amazing.
What was the "Class A time" for the Marines 20 years ago? No offense but if you broke 18 minutes (6:00 mile) for the 3 mile I'd be surprised. Kipchoge just ran a 4:30 mile for 26 miles. Hell, the best marathoner the US had in the 2000 Olympics ran a 2:30. Literally a half hour slower than Kipchoge.
> No offense but if you broke 18 minutes (6:00 mile) for the 3 mile I'd be surprised.
Curious, but why? That's an extremely achievable time for anybody who is athletic and trains.
(no disagreement that 4:30 pace is vastly more difficult than 6:00)

#168Reminds me of this post on HN from 5 years ago: what will it take to run a 2 hour marathon? https://news.ycombinator.com/item?id=8439408 Unfortunately the linked article seems to have disappeared. I wonder if today's record was run with those special Nike shoes with the blades inside... The ones that supposedly give you a 1 percent boost or something similar... If you have shoes that give you such a boost, is it dopi…
I remembered this article also, thanks for digging it up again. Its predictions were pretty spot-on: - Predicted in November, actual mid-October - Predicted in Debno, actual in Vienna, but both are very flat courses (I can't find if Debno is flatter) - "The pacemakers will form a human wall" - yes, pacemaker strategy seemed critical here. - "Mindblowing pay-day" - No clue, no articles seem to mention it. - "Kenyans w…
Large parts of the track were re-paved specially for this event with fine-grained asphalt to avoid holes and unevenness. The re-pavement was paid by a project sponsor.

Dude, I get it. It wasn't a race. But it was damn close to race conditions. Pacemaking is a situation that regularly happens on race day. There was no giant fan. It was basically race day under ideal conditions. You are obviously not a runner, and don't appear to have an understanding of how important certain rules are (or aren't) and yet want to enforce your judgment on everybody else. Now that's what I call Bullshi…
It was damn close to a race, and they got a result that is damn close to the world record.
It was 121 seconds faster than his own world record.

Didn't the British do something similar in the Desert Campaign during WW2, burying supplies to be recovered later. The Long Range Desert Group perhaps?
Reminds me of the rescue of the Thai football team too, where the divers were dropping oxygen tanks further and further in to reach the boys.
