That's running 42km at 21km/h… Anybody who already tried to run a sub20 5km (5km at 15km/h) knows how crazy this is.
a normal recreational runner could keep up for between 400 and 800 meters.
not even one mile!
Eliud Kipchoge Breaks Two-Hour Marathon Barrier

Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#152That is, while impressive, pretty meaningless. The thing is, that sports are defined by their rules and to the best of my understanding the long distance running rules are written to prevent teamwork. (Unlike cycling, which is explicitly a team sport.) Basically, the two hour mark is important in the specific circumstances of Olympic marathon, and was broken in a different sport. To broaden the discussion a bit, it s…
How are they bending the rules if they try to prove that a human can run a marathon distance in less than two hours? I am not arguing that he has run a marathon below 2:00, but he is the first recorded human that has achieved such a feat - which is kind of a barrier many people have tried to break or at least recognized to exist - even though it has required them to remove all possible outside factors like wind and t…
the human had artificial draft from a car and humans, so the human alone didn't run the marathon in less than two hours.
Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#153While an amazing achievement, this seems quite artificial. A team of human pacemakers and following a car going at just the right speed. Non paywalled link with photo of laser-guiding pace-car: https://edition.cnn.com/2019/10/12/sport/eliud-kipchoge-mara... I can't find anything about anyone doing it on a treadmill before this, though. Maybe that's harder for some reason? Eliud Kipchoge's world record is 2:01:39, whi…
Well the first 4-minute mile was achieved in a similar manner and for some reason it is well known in the popular imagination. To be honest I think these arbitrary marks of achievement are all very artificial and more about good PR more than anything else. Personally I think the 2 hour marathon is slightly less arbitrary than the 4-minute mile but breaking it was only a matter of time.
they did not have an suv to draft behind, and the pacers had to keep up from the start

A device like google glass wouldn't be much heavier than their usual glasses.
Every once counts. Also, it would be a pain to keep on while running. Are there any ultramarathon runners that wear glasses while they run?
Different sport altogether, it’s more the endurance so the pace is generally lower. Also you usually won’t have much support along the way so carrying water & food is pretty essential.
Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#155It should be noted there are, at least 3 things here that make this quite a bit different than a normal marathon: * questionable shoes, but personally I'm fine with this, its just better shoes! * the pace car is too close providing large aerodynamic advantage * the pace makers aren't in the race from the start, might as well just let the car get even closer and dispense with the charade entirely The last two points m…
I watched the video. The pace car was too far in front to provide any real aerodynamic advantage at that speed.
Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#156Reminds 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…
> If you have shoes that give you such a boost, is it doping? Definitely not, as doping is about drugs. It may be cheating though.
By definition it's impossible to "cheat" in an event like this. It was an exhibition with no rules, not a sanctioned race.
Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#157So 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 :-)
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?

So, if they wanted to prove that a human can run a sub 2 h marathon distance, then why is not the entire doping arsenal in play? Similar, one could probably improve on the record by driving behind the runner with a car with an really big fan. Neither of that was done to prove that a human can run sub 2 h. My argument is now, that would shatter the spectacle. The NYT would not report on the first fan assisted sub-two…
While I do recognize that the bar is arbitrarily set I do still believe that there is a significant difference between a scenario that could very well happen by chance in the normal world (optimal weather, zero wind, optimal surface) compared to doping and pushing the runner with wind from behind.
Well, we have arbitrary rules, that produce a result close to an arbitrary timespan. Then you change the rules in a way that breaks the timespan, in a way that is compatible with an ill defined cultural expectation what is essential and what is incidential of the original rules.
I mean, of course to I realize that a fan would violate some expectation of long distance running more severly than pacemakers and a specially prepared course, I just say that to call it sports, other teams of runners should be allowed to compete according to the same rules.

Define "could", my intuition is that there is a vast population of men who couldn't complete a one mile run (right now with no training)
Interesting. Your intution bascially says that vast population of man could not walk a single mile. Because factor of 3 means walking, not running.
Well a brisk walk (from memory) is about 15 minutes a mile.
So people under the age of 10 and over 60 probably start having a non-negligible numbers of people who can't complete a mile in 15 mins.
And then you have an obesity + overweight rating of 57.6% in the USA according to Wikipedia (and this may not cover people who are not overweight but physically fit) and you can start seeing how maybe not everyone can do even a 15 minute mile walk.
For the record I know BMI is a bit of a weak metric for covering obesity given that anyone "swole" will have a very high BMI...
Re: Eliud Kipchoge Breaks Two-Hour Marathon Barrier
#160Anyone have estimated of how many calories he burned during this run? I wonder how much he ate before starting and when? Are they allowed calorie dense drinks during these runs? I do not do runs, walking sure, so I am just really curious how much it takes for the human body to do this type of run
Kipchoge probably burned about 2500 kcal according to online calculators. Maybe slightly less in reality due to drafting off his pacers and having an exceptionally efficient running form.
Runners can drink anything they want as long as it doesn't violate doping rules. The elites all have customized carbohydrate mixes.
