User carb-loading advice for endurance

AngloSacks posted carb-loading advice on X on May 21, adding to the steady stream of race-week nutrition guidance circulating among recreational endurance athletes. The post warned runners against beginning intense training with depleted muscle glycogen and argued for timing carbohydrate intake ahead of hard efforts. The advice referenced marathon preparation and long runs, but did not give a specific carbohydrate target in grams per kilogram. The post appeared on the user’s X account on Thursday. ### Why did this post focus on glycogen depletion before hard training? The May 21 post said athletes should avoid entering intense workouts with low muscle fuel, framing glycogen depletion as a preventable mistake in marathon preparation. The user’s point was practical rather than technical: carbohydrate intake should be arranged so runners are not under-fueled before key sessions. (x.com) Muscle glycogen is the stored form of carbohydrate that endurance athletes draw on during sustained and higher-intensity work. AngloSacks’ advice centered on preserving that supply before demanding sessions rather than trying to complete race-week training on reduced carbohydrate intake. ### What exactly did AngloSacks tell runners not to do? AngloSacks advised against using a low-carbohydrate approach the day before a long run during race week. (x.com) That was the most specific behavioral recommendation in the post and tied the broader warning about depletion to a concrete pre-run decision. The post also suggested that carbohydrate timing matters, meaning intake should be matched to when a demanding workout or event is coming. (x.com) AngloSacks did not present the advice as a full nutrition plan, and the post did not include a menu, product list or formal loading schedule. ### Did the post give a formal carb-loading formula? The May 21 post did not provide an exact grams-per-kilogram prescription. (x.com) That leaves the advice at the level of principle: maintain carbohydrate availability before long or intense efforts and do not deliberately cut carbs immediately beforehand. That omission matters because carb-loading guidance often turns on body weight, session duration and race distance. (x.com) In this case, AngloSacks’ post was narrower, describing what runners should avoid and when they should think about carbohydrate intake, without setting a numeric target. ### Was this aimed at marathoners or endurance athletes more broadly? The post referenced marathon preparation, but the language was broad enough to apply to endurance athletes preparing for long runs and other hard sessions. (x.com) AngloSacks used marathon context to illustrate the point, not to limit it to race-day fueling alone. Race week is when runners often adjust mileage, intensity and meal planning, and the post addressed that period directly by warning against low-carb habits on the eve of a key run. (x.com) The emphasis was on preserving training quality rather than experimenting with depletion strategies. ### Where would any added detail or follow-up appear? The X post was published on May 21 under AngloSacks’ account, and that is where any clarification, follow-up replies or added carbohydrate targets would most likely appear. (x.com) The post available Thursday contained the core advice but no quantified loading plan.
