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.
For the previous attempt at the Breaking 2 event at Monza racetrack, they used a Tesla as a pace car.

> the shoes I guess - I don't know how big an advance these are The pacers wore Vaporfly, Kipchoge wore a prototype. The Vaporfly have been shown to actually make a difference of around 4%. https://www.nytimes.com/interactive/2018/07/18/upshot/nike-v...
But he also wore Vaporfly for his 2017 attempt, I thought - I doubt the prototype is 4% on top of that, or even 4% compared to what top-class runners were wearing before.
At Monza he ran in 2:00:25 and this race took 1:59:40, that's 0.62% faster. Definitely within reason for a technical improvement.
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…
You are perhaps a bit unfamiliar with long distance running. Team work can be a part of long-distance running. Pacers can help with the mental effort required to run at a particular pace; they can shield the runner from the adverse effects of wind during a race; they even help with the time keeping and dealing with crowds of spectators impinging on the course. Should be pacers be a part of marathon racing? Perhaps no…
Link to full video in case you didn’t watch it live (in which case, what’s wrong with you?): https://youtu.be/k-XgKRJUEgQ This is an extraordinary achievement. It was just last September that Kipchoge set the W.R. time of 2:01:39[1]. It’s only a matter of time (no pun intended) till sub-2 is broken in competition. Probably at Berlin. Just knowing it’s possible is a huge barrier to break through. I’ve run over two doz…
A well-known secret in running circles - many Ethiopian and Kenyan runners have dubious official birth years including Eliud Kipchoge.
from https://runningmagazine.ca/the-scene/zane-robertson-swears-k...
(Zane Robertson, one of two identical twin brothers from NZ who live & train in Kenya and ran 2:08:19 for the marathon):
"That’s when Robertson got involved, commenting that Kipchoge is over 40. When challenged on this, Robertson claims “There [sic] passport ages are all fake so they can cheat Jr’s and get contracts,” and claiming authority on the subject because he lives and trains in Kenya, along with his brother."
Jr's refers to races for men & women under 20 years old.
It's much easier to do well against non-African teenagers if you're several years older and have trained for that much longer.

This kind of comment really depresses me. Someone achieves something absolutely amazing and some random commenter on the net will be happy to belittle it in every way that they can think of.

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.

The benefit of the support runners wasn't just to help him keep pace (he could probably do this with music). They also provide a drafting help to limit any head-on air resistance.
Is that significant when running?
Even a 1% benefit is significant, considering that he beat the 7200 second goal by just 20 seconds (0.28%).

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 special…
They didn't change the rules. That is why it is not a world record. Because they broke specific rules to see if it was possible at all before attempting it in record eligible conditions. The importance of the attempt is that nobody knew if it was actually possible to run a marathon in under 2 hours without performance enhancing substances, i.e., if the theoretical estimate was unattainable in real world attempts. The…
However, a very concrete example would be bringing him water, as opposed to slowing down and grabbing it. Something that I can easily imagine brings 20 s, and therefore we still do not know, if a 2 h marathon is possible.
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…
Oddly enough, caching? Something you couldn't possibly compute with a reasonable response time is simply cached the first time and served until it expires.

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 :-)
