Because calories simply do not matter. At high intensities of working out, it's the amount of carbohydrates you can consume that allow more fuel to be burnt. "In the aerobic exercise domain up to ~100% of maximal oxygen uptake (VO2max), CHO is the dominant fuel, as CHO-based oxidative metabolism can be activated quickly, provide all of the fuel at high aerobic power outputs (> 85-90% VO2max) and is a more efficient f…

Calories do matter (obviously, as energy intake is the entire point) but as you note the specific form that the fuel takes matters. However "carbs" is a catch all that includes plenty of things that (I assume) would be of similarly minimal use in this scenario. The calories need to take a very specific chemical form for this to work.

The wording is certainly confusing here, but yes the calories don’t matter as much as the form. Eating protein and fats simply give you minimal useful calories during the race. Even most carbs won’t be useful if they are more complex.

> 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…

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!

In a two hour race that’s still 800 bonus calories, that’s something.

The race to tolerate lots of carbs is usually something you think of in 8 hour Ironmans. The good part is you can do most of it on the bike, which is much easier to eat as you go. As far as I know, many elite runners were doing like 50% water, 50% sports drink and consuming way under 100g.

Better weather has, to the best of my knowledge, never been part of marathon record keeping. People do note in accounts of (e.g.) the Boston marathon that the weather was particularly atrocious in some years (hence a general slow down across the field), but weather "aided" fast times are not considered illegitimate or even worthy of note. Obviously, barring wind, which is why some marathon courses are not eligible fo…

Correct. Boston is a net downhill point-to-point course and not record eligible under World Athletics rules. https://worldathletics.org/records/certified-roadevents

No point to point courses are eligible, because of the "risk" of a wind assist.

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…

The leaders were burning a lot more than 100kcal per hour. I think you mean 100g of carbohydrates per hour.

Not burning, eating. They are eating 100g of carb per hour. Burning 1000+ calories.

AI told us we should add glue to pizza

Is that not what tomato paste and/or cheese is? Food glue? The other ingredients would fall off too easily otherwise.

Or did the AI say we should be using PVA/cyanoacrylate/polyurethane glue or something?

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.

Well if they’re sold in stores and next year everyone will have a pair, then it’s not going to be an unfair advantage, is it?

There is a whole class of running shoes banned from various competitions.

Essentially the argument given was too much advantage came from the shoes and they didn't want racing to be about shoe technology development.

Wow, that’s ~13 mph, basically a full-on sprint for a mere mortal. Absolutely insane.

The fastest marathoners are moving at 4m30sec per mile or faster. Very few mere mortals could run that fast for even 100m.

We used to be amazed when I ran cross country in high school that these pro marathoners would best all of us in our approx 5K(3ish mile) races and then go on to repeat that distance multiple times.

It’s totally remarkable.

A purist might want the athletes to wear the same gear as Pheidippides

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.

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...
