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.

> burning a hundred calories GP left out the units but is clearly talking about grams ("absorb ... 100 carbs per hour"), not calories (no one needs training to absorb 25g/hr). Carbs are 4 kcal/g. 100g of carb (400 kcal) an hour isn't replacement level for even casual athletic efforts, but it does mitigate the loss of glycogen in muscle somewhat.

Exogenous carbohydrate doesn't spare muscle glycogen, only liver glycogen.

While I know competitors want to always strive to be the best, as a completely normal human who struggles to complete a half marathon under two hours, I do not feel bad for the guy. He’s still one of the only two people to do it (outside of the very controlled run from Kipchoge). Not a feat to feel bad about at all.

The majority of people in the world cannot complete a half marathon, let alone under two hours. I was pleased to train enough that I managed under three. You're doing great!

A majority of people won't run 1 km without needing a rest afterwards.

There were recent tests (in France I think) in schools where 50% or something could not run 1 km (sorry I don't have the details on mobile). These are children who have infinity energy (source: parent).

A typical adult won't make it to 1km (source: going back to sport and dying on a 2.5 km run)

Much like the road bikes that cost as much as a sedan, unless you are competing on a world stage, these aren’t meant for you. I’m sure someone will happily sell them to you if you enjoy wasting money.

> unless you are competing on a world stage, these aren’t meant for you. There’s a lot of people trying to get a 3 hour marathon or some other goal where chasing the marginal gains is worth the cost to them.

But if you could only achieve it by adding the shoe isn't that a bit hollow?

If you are a 3:02 marathoner in normal shoes then run a 3:00 in a super shoe, you are still a 3:02 marathoner in normal shoes.

We never had any for Lance Armstrong until he confessed.

His comment is more of a general commentary that east African countries are notorious for doping.

Like, if we find out the top two finishers here doped very few would be surprised.

That said - it's still an amazing accomplishment.

It was never about the runner, it has always been about technology and innovation. Shoes tech is just one of them. Better nutrition, novel training techniques, better air quality etc. Of course innovation in shoes will have a bigger marginal impact (because physics).

Can't help but think that the wins and records done barefoot and without refreshments in the 1960s are still a bit more about the runner than running with essentially spring loaded shoes, lab-optimized nutrition gels, computer optimized pacing strategies and multisensor real-time measurement devices. It's also somewhat ironic for a race supposedly modeling a messenger running the distance in an emergency situation.

Also makes wonder question did the messenger participate in hard cardio training before. Meaning the fighting. Or do some messengering before.

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?

AFAIK 5:4 is just the lowest ratio they've tested. Personally I use table sugar (1:1) and can sustain rates above 100g/h. Haven't hit the ceiling yet, don't really feel the need to explore where that is yet because exceeding the absorption rate comes with the risk of diarrhoea which is bad at any time but especially when you're in the middle of a training session and who knows where the nearest toilet is.

Gut training is consuming large amounts of carbohydrate (preferably in the same form you intend to use when racing), yes.

Stunning results at the top of the field. Some interesting takeaways on both fuelling and shoes.

Do we know of any adverse effects on such long term consumption of that amount of simplest carbs? While good source of immediate energy, simple carbs are basically a slow acting poison to various internal organs and over time bring stuff like diabetes. Its great they don't sit idly around in the body and get transformed into fat but rather they are burned in muscles, but still flooding body again and again with this…

> simple carbs are basically a slow acting poison to various internal organs and over time bring stuff like diabetes.

Do you have any evidence for this? The problem with simple carbs (if you don’t already have insulin issues) is that they’re easy to digest and provide minimal satiety so you end up consuming significant calories.

But as far as I’m aware there is no evidence that they’re worse for you than the rapid calorie addition.

My predicted half time is under 2 hours and I was sedentary for years before starting to run 9 months ago, and I'm 40 years old. Endurance sports are quite accessible and don't require that much time, effort, or talent to get way better than the vast majority of people, it's just consistency.

I've been an endurance athlete most of my life, running 100 miles at 17, a 5:30 mile at 50, and lots of other stuff in between. I know that a 9min/mile pace is "easily achievable" by many folks, which is why I noted that millions or billions of people could do this. Nevertheless, I think it is really important to not overstate how achievable this is - there are many more people who could not do this than could, I thi…

That is a steep drop in mile pace between ages 50 and 62 you had. Is it just age/genes/luck or did you have some sort of injury in between?

Considering that you can still do a decent sprint over 400m and have the endurance for ultra marathon distances at lower pace, it sounds a bit odd.

It’s either scientific or it’s not. Don’t forget that two people actually ran under the two hour mark.

Not sure I understand what you mean by "scientific." If you mean exactly reproducible, then almost nothing in athletics fits that definition. Every record in baseball, football, etc. would fail that definition.

Yes. That is what I meant. Sports records are nonsensical.
