It's not a letter. Just a podcast episode! The authors are fixing the paper. They were very gracious and acknowledged their errors!

He he he - the two glucose pool model is now 'key biology'! The level of hubris is almost unbelievable... (-:

Hi Kristin @KristinSainani. This letter identifying irregularities in paper studying hi rates of CHO ingestion on performance, will it be made public? Key biology is 2 glucose pool model.

What makes play, especially to adults, so rewarding? Why is playing fun?
It’s about honing predictive processing, writes @sweatscience—“When we play, we deliberately choose to increase uncertainty in order to experience the pleasure of reducing it”

If you’re curious and always itching to know what else is out there, ‘The Explorer’s Gene’ by Alex Hutchinson (@sweatscience) is a wonderful read.
It will expand how you think about curiosity, risk, and exploration.
Here are some of my favorite pages:

Norway clearly doomed. I mean, where's the pasta?
Because we all know that "Carbs are King" as all elite athletes and the scientists who study them know to be true (sarcasm).
(P.S. The player pictured is pretty much a carnivore. And the greatest football player, Messi, quit the pasta decades ago when he was gaining weight and playing poorly).

🚨🚨🚨 Norway have brought their entire kitchen to the 2026 World Cup! 🇳🇴🍽️✈️
• Norway has decided to send huge quantities of traditional food with the national team delegation to the United States to help players perform at their best.
• The shipment includes:
🐟 300 kg of fish
🍊 6,000 oranges
🧀 116 kg of traditional Norwegian cheese
• A renowned Norwegian chef is accompanying the squad to prepare meals daily.
• The main goal is to ensure players continue eating the foods they grew up with, helping maintain their focus and physical performance throughout the tournament.
• Norway has used this approach before, including at previous Olympic Games, where it regularly transports national food products to support its athletes. 🇳🇴🏆🍽️

My pleasure. This is a very heated topic at present. Need to bring all the evidence to the debate, not to selectively ignore some. Which includes acknowledging that elite athletes are doing what some scientists like myself says is probably unnecessary. But yet they are convinced that it works. And, with respect, they spend 24 hours a day thinking about going faster. Could they be wrong? Seems improbable. Could we be wrong? Of course. Especially if the mechanism of action has not yet been described and so we are missing it. Time and more good science will provide the definitive answers. Which are desperately needed.

Thanks Francesco @Fem1964. What do you think is happening with repeated high doses of CHO ingested during prolonged exercise by elite athletes like Tour de France cyclists, Ironman triathletes (Blummenfelt) and runners like Sawe and Kejelcha, all of whom clearly believe it has a large "fatigue-busting" effect and their exceptional performances seem to justify their opinions? Would value your opinion as you've obviously approached this from both the metabolic and neurological aspects which few of us have.

Hi Tim, Not a non-believer, more sceptic of simple explanations. CHO can help when substrate availability matters, especially in longer events, but effects vary with context. Placebo/expectation and oral CHO sensing may alter effort perception. That’s mechanism, not dismissal.

Unlikely to win award for most popular recent article in sports nutrition. @PhilipPrins11 @AKoutnik @LoreofRunning1 @PaulBLaursen @sweatscience. Expect usual criticisms - not elite athletes; underpowered; cherry 🍒 picking; lab findings irrelevant to real world of competition etc

Fuelled or Fooled?
Our latest Sports Medicine paper examines the evidence for ultra-high carbohydrate intake in endurance sport.
Bottom line: promising in theory, but current evidence is insufficient to support broad recommendations for most athletes.

You are correct to question this @paul_fendler. After the recent world record marathon performances, both companies sponsoring the 2 athletes reported what the athletes had been offered during the race, not what they had ingested. The number were over 100g CHO/hr for both.
A recent study of runner in the 2025 Western States 100miler showed that most aimed to ingest more than 60g/hr and some as much as 90g/hr. After the race >60% reported gastrointestinal symptoms during the race. I'm not sure if the authors looked for any association between CHO intake during the race and the likelihood of developing gastrointestinal symptoms.
As we now might agree, if very high CHO intakes improve performance, they likely act via the brain, acting as an ergogenic drug, so to speak.
If so, why bother to take the agent when you are not fatigued. Why not wait until the final 30% of the race? That makes much more sense and might reduce the risk of gastrointestinal upsets.
Yomif Kajelcha for example pre-loaded with a large volume of a concentrated CHO drink in the hour or so before the London Marathon. This would be the logical choice if the drink is acting metabolically. But if it's acting via a brain mechanism, that would seem unnecessary. Rather wait until the effect is really needed say beginning after 16km.
But that is just a thought.
