The LetsRun thread on this is pretty great, starting with a heated debate about his shoes. Were they too springy? https://www.letsrun.com/forum/flat_read.php?thread=9640871

Wow, that was not heated but toxic. I had to nope out of that after reading the first 2 pages.

So 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…

This is also why rockets have multiple stages. A single rocket can’t make orbital velocity with significant cargo, but a bigger rocket can get the small rocker part of the way there. It works because the second stage’s lower weight allows for smaller engines and fewer fuel tanks etc.

Earlier quoted context omitted.

https://en.wikipedia.org/wiki/Drafting_(aerodynamics)#Runnin... : ”Drafting behind another runner can conserve energy, although the effect is less than in cycling due to the fact that speeds are lower.” There also is a psychological effect. It is easier to keep a constant pace if there’s somebody in front of you that does it, too.

So use an AR headset to put a virtual person in front of you keeping a constant pace?

What possible benefit would AR provide in this situation?

Reminds 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 who dominate world marathon lists generally do little, if any, weight training, which may represent an untapped source of improvement." - "To his normal preparations he added workouts focused on core strength" (though unclear if weights were a focus).

- "5' 6" and [120lb]" - Kipchoge is 5'5" and 125lb.

- "access to [technology] we can't imagine" - the shoes I guess - I don't know how big an advance these are - compared to his last attempt the pacemakers and location seem more relevant.

- "early 20s" - complete miss.

- "I’m saying the year is...2075" and two generations late.

Interestingly, it predicts very precisely the characteristics of the run and the runner, except for time - both the runner's age, and the time until it would happen.

I 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.

In the Marines you may not have been 5' 6" and 126 pounds with a BMI of 20.3. Kipchoge and his pacers have a similar physique.

That 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…

> They succeeded, but they only succeeded in a game of their own invention. As opposed to the natural phenomenon of running through the streets of Berlin/NYC/Boston/Chicago/Tokyo as God intended? All sports are a game of our own invention. You are also incorrect about long distance running rules preventing teamwork. Marathoners definitely work together.

Sports are a game of our own invention, correct. However, they sat down and made specific rules for this single spectacle, aka a game of their invetion. That is categorically different, and that it is categorically different from marathon is my entire point.

On long distance running, you are correct I know a lot more about cycling and it seems every time I see anything about running discussions is, when people say that they don't want to become cycling with team captains and domestiques who get them water.

Actually sounds very similar to how the rocket equation works, too.

Most meaning the median person ? I doubt it

5 mph, not much more than walking speed? I have doubts about keeping it up for 5 hours, though.

I think running 5mph for 5 hours is a very ... achievable goal for the median person, but I don't think I would put money on the median person, or at least, American, completing that time without additional training from their current condition.

If you took a random sample of people -- or at least a random sample of people 18-50 with no outstanding health issues -- and put them on a "couch to marathon" 6 month training program, yeah, I think you could plausibly get a median finish of 5 hours (for comparison, the Boston marathon has a median finish time of a little under 4 hours).

I honestly wouldn't bet on the median person with no training getting off the couch and moving 26.2 miles in less than ~10 hours.

Maybe for keeping a safe distance without having to eyeball it, or for avoiding the fumes.

Might want to use an electric car to avoid the fumes. I do wonder if the car, even a larger distance ahead, does more for drafting than a human in front of the runner.

I don't have the source on hand, but there was an interview with the person who designed the unusual reverse-V shaped pacer formation, where he said that if it was up to him there wouldn't be a car in front of the runners. The goal is to have as much air as possible hit the front pacers.
