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

The fastest 1km I ever ran was around 3m20s, I felt like I was sprinting, and was fully cooked at the finish line. Afterwards I did some quick numbers and realised the average marathon runner was not only going a lot quicker than I was, but they were doing it for a further 41km

You've proven you can run one kilometer. You just need to prove that if you run any km, you could run the next km, then you're done.

> 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 mimicking race-day protocol in training. The hydrogel technology they have developed over the past 10 years now allows athletes to absorb 90–120 grams of carbs per hour without GI distress. That common knowledge, nothing revolutionary here. Ther…

> Third, his steroid/peds program is on point and his body is responding well to it. Do you have any evidence of this?

There are two kinds of athletes that win global track events: - athletes from areas with bad doping enforcement (remote places in the mountains of Kenya, Jamaica) - athletes from countries with tons of surplus biomedical expertise (USA and other western countries)

Was the barefoot movement ever about running faster? I always thought they sold injury prevention by strengthening tissues that running shoes tend to over support.

Yes, that was the claim but it was never really backed by evidence. Vibram settled a lawsuit over false claims that their minimalist shoes reduced the risk of injuries. (I still like those shoes myself and use them on some slow recovery runs.) https://www.bbc.com/news/business-27335251

My understanding of the advantages from barefoot running is that it was more about helping you lock in stride and form while preventing injuries outside of race days.

I thought those carbon plate shoes were barred from competition???

Posted elsewhere, they have tightened regulations to clamp down on the "franken-shoes". 40mm stack height maximum One carbon plate only (some shoes were including a second). Must be on sale to the public for Puma makes a shoe that's non-compliant with the above (two plates, not sure about the stack height), for what it's worth.

As someone whose tallest shoes have a 10mm stack heigh, 40mm is crazy high!

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.

> 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.

There's a whole industry of hiking gear that has been steadily trading weight for durability. I only hike in running shoes (altras) which only last me 400 or so miles. It's way less durable than my old boots.

I doubt this sort of thing will translate, but I wouldn't put it past hikers to opt for something less durable to shave a few grams.

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…

> Super shoes. Most shoes have carbon plates in them now, they act as a spring, storing energy and propelling athletes forwards. I wonder where that leaves the barefoot movement. Hype dust?

I still prefer to run in minimalist shoes because I like to feel the ground. The new breed of running shoes seem comically thick to me. I tried a pair for a few weeks, they still feel wrong. If a company would make a low stack height shoe with one of the new super foams, I’d probably buy three.

No competitive distance runner since like Zola Budd ran barefoot or minimal shoes. The carbon plate revolution is the main driver for drop in times over the last 5+ years

I’d consider the old models of Nike Waffle race flats pretty minimal, and those were ubiquitous 15-20 years ago.

> 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…

I've read that even if you absorb it all, there's some question about whether it's useful. This Alex Hutchinson article suggests, among other things, that it may spare your fat stores rather than your muscle glycogen: > Even if you can absorb 120 grams per hour, it might not make you faster. In Podlogar’s study, cyclists burned more exogenous carbs when they consumed 120 rather than 90 grams per hour, but that didn’t…

Kejelcha is 6'1" and under 130lb.

What fat stores?

> One athlete broke the women's world record Not so. She broke a record for a female-only-pacer marathon time. The women's world record was much, much faster.

To add some color here: It is very helpful to have someone pace you so that you can run an ideal pace without worrying about whether you are running the right speed. However, the rules require that pacers start with you [0], which means that by definition if you are running faster than anyone has ever gone before you have to run some of the race alone. However, because marathon are often mixed gender and the best mal…

Having a pacer start with you seems to defeat the purpose? I’d prefer someone fresh and full of energy to jump in halfway to carry me through the end.

Is there anything here a people who should be dieting could learn here? I’ve found when running, every 3-4km if I do t have sugars/gatorade my blood sugar gets so low I end up almost confused… running suburban streets is tough because I’ve got to cross the road when I’m midly delirious!

How far are you running total, both per run and per week?

Running will absolutely help your health, but on its own it's unlikely to get you thin. It's hard to burn enough to make a big difference without it chewing your body up in other ways - especially if you're overweight and out of condition to begin with, and so a bit more susceptible to injury than skinny runner types.

Thinking of it as a calories in/out equation is counterproductive for most people, if it boosts your cardio health, gets you more active and maybe converts a bit of body fat to leg muscle, that on its own is a win.

Certainly no harm in having a swig of Gatorade every couple of km if it helps you go further, anyhow.
