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.

> That common knowledge, nothing revolutionary here.

I've never read about that. So it's not "common knowledge" - except maybe in the running community.

I like your comment for putting some facts into place (how far you can go with common options). But as I never heard of this before, I have no idea how common it actually is and the effects and the science around it, what research does say to this, how and why this is used in other sports - or why not.

> 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?

Yes but the science is actually achieving that and finding the limits. It used to be thought that 60g carbs/hour was the limit, then 100g, now it’s thought to be 120g.

It’s also about the methods of achieving that under stress without spewing it all back up. Ironman athletes would stuff their faces on the bike under the assumption that this volume of carb absorption wasn’t possible while running.

Some of the challenge in research will come from competitors not wanting to publish results to maintain an edge. It is mitigated by the visual of the race by (you can see athletes pounding carbs), as well as the nutrition companies wanting to sell more product. This will cause them to publish some information to convince us amateurs to quadruple our purchase volume ;-)

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 cours…

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.

From the picture it looks like he is only wearing a watch and there is perhaps a little bulge on his left side.

Damn was thinking km/h. Thanks for the correction.

You actually can get a ticket for driving 13 in a 25, at least in the US, so you're not entirely incorrect.

Fair enough. My kids are learning to drive and “how fast should I go” is a constant topic in my family right now.

Just yesterday I saw a learner driving at what seemed 10 mph in a 40 mph road, creating a massive queue.

I normally consume 90g of carbs per hour when long distance biking, so do a few other riders I know. No GI issues. I use Skratch some other guys like Precision.

It's much easier when cycling and there is much more freedom with your breakfast choice and timing. You are stable on the bike. When running there are constant vibrations and up and down movement that can easily upset your stomach/intestines.

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…

I don’t think there is any elite level sport that doesn’t trade long term health for performance in competitions.

They collected samples every 5k in the 30k long run before the marathon, see Substrate section in http://athlete.maurten.com/

There's something about the London course today that made for very good running. Three athletes broke the men's world record. One athlete broke the women's world record, and three were in the all time top 5. An Irish record was also broken, likely other countries too that I'm not familiar with. Not to take anything away from the achievements. Incredible running.

> 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.

what does female-only-pacer even mean?
