A purist just wants it to be about the runner not the shoe.

Purism is extremism about a thing. Pick a thing, be purely about that thing. I used to love F1 for the tech that would filter down to my car in ten years time, but that is not a thing anymore. I for one love the advances in technology in something as supposedly simple as a shoe. And maybe I'll get to use it on a hike in a few years.

These shoes are practically disposable. They trade longevity for noticeable gains in performance. Even the tier below don’t last very long. This is not tech that is going to filter down to your hiking boots.

Those shoes are gonna sell like crazy now but it would be hilarious if they were to be found to have been giving an unfair advantage because of some mechanical property of the shoe.

The Nike Zoom Vaporfly's already had set this precedent years ago: https://www.nytimes.com/interactive/2018/07/18/upshot/nike-v... The big improvement then was a carbon plate. Adidas (and others) followed suit. The subsequent improvements since then have been marginal but the margins are thin at that level. In this case the big advancement has been the weight of the shoe. EDIT: Also it's worth noting these shoes are…

Do these new Adidas shoes have anything major over the Vaporfly shoes? Maybe they are a bit lighter?

I think the big story here may be the nutrition science to get these guys to absorb a lot of carbs during the run, more than the shoes.

I'm a runner, and it's a bit sad that distance running is not longer purely about the runner.

Based on the quote below, next thing we will see is a "constructors championship" similar to F1 for winning shoe constructor in the 'major' marathons :-(.

" This dominance continued in 2024, with adidas athletes wearing Adizero models winning six out of 12 World Major Marathons – more than any other brand."

and yes, of course i race in super shoes :-).

Stunning results at the top of the field. Some interesting takeaways on both fuelling and shoes. Maurten spent months working with Sawe and other runners getting their gut capacity trained so they could absorb and burn 100 carbs per hour[0][1] > The Maurten research team was embedded with Sawe’s team in Kenya for 32 days across six trips between last and this April. They were training his gut to absorb that load by m…

> could absorb and burn 100 calories per hour burning a hundred calories an hour is trivial. Most people will burn 100 calories per mile when walking or running, and more if moving as fast as these athletes, and many, many humans can do this for far, far longer than 2 hours. It's the absorbtion that's the challenge. Maurten is not somehow alone in the particular stuff they've developed - ultra runners are generally s…

Where does discussion on gut training occur? All I know is you need a 5:4 ratio of glucose to fructose? Then when you train, you use the gels and the more you do it, the more capable your gut gets at absorbing without distress.

Is that all the science to it?

If I wanted to know what an LLM thought (I don't) I would go ask an LLM.

One person sharing what an LLM thinks is probably better for the environment than each person asking...

I'll trade a little bit of damage to the environment in exchange for keeping meaningful communication between human beings alive and well.

It sure would be great if the LLM in question would cite its sources so that we could verify whatever source it ingested this text from.

[flagged]

Indeed, I've seen LLMs begin to cite their sources, which is a commendable advancement and something that I've been asking for since the beginning of this craze: LLMs as librarians, not as summarizers. But if the commenter had a reputable data source, they should have quoted it and linked it.

Wow so he was absorbing 400 calories per hour with this gel, but he was likely burning 3-4x that amount (or even more) while running 13.1 miles per hour!

Your body stores roughly 2000 calories in glycogen. They are burning calories but nowhere near the amount a middle pack would be at this pace.

So ~2800 calories of carbs with some fat being burned.

Too bad, you could run a lot faster in a vacuum...except for that whole breathing thing.

Can't wait for vacuum track racing on the moon. https://link.springer.com/article/10.1007/s00421-010-1410-1

Posted to my in-laws, who asked how: Super shoes. Most shoes have carbon plates in them now, they act as a spring, storing energy and propelling athletes forwards. Better understanding of fuelling. Most athletes are taking between 100-120g carbs (sugar) per hour. Bicarbonate of soda has also been effective. Better planning tools. Athletes look at elevation, headwind, tailwind and will plan a strategy around going har…

> going harder into the hard stuff and knowing when they can back off and rest.

Why is going harder in the hard stuff and easier in the easy stuff more efficient or faster than vice versa? I imagine arguments either way:

Going harder when it's easy gives you higher ROI. Or maybe going easier when it's hard is just too slow. And maybe that is too simplistic: Maybe it depends on how hard; that is, maybe there is a threshold.
