Steak Before the Marathon: What Athletes Actually Ate (And Why It Was So Wrong)

In 1968, as Kenyan runner Kipchoge Keino prepared for the Olympic marathon in Mexico City, his coach had a simple piece of nutritional advice: eat meat. Red meat, specifically—steak, beef, whatever protein you could get. The logic was straightforward: muscles are made of protein, so feed your muscles protein. More protein meant more strength. It was a theory that had dominated athletic training for decades, and it was almost entirely wrong.

Keino finished second in the marathon, which was a respectable result. But he did it despite his nutrition, not because of it. He was running on conventional wisdom that would later be recognized as fundamentally misguided. His body was a sophisticated machine, but his coaches were fueling it like it was a 1950s car engine—thick, rich, heavy fuel that the body struggled to process efficiently.

The gap between what we now know about athletic nutrition and what athletes actually ate just 50 years ago is staggering. And it reveals something important: we were confident in advice that was demonstrably harmful.

The Protein Obsession

The idea that athletes should eat large quantities of protein is rooted in a basic misunderstanding of how muscles work. It's true that muscles are made of protein, but eating more protein doesn't automatically translate to stronger muscles. Yet for most of the twentieth century, this leap in logic dominated athletic training.

Coaches in the 1950s and 1960s would prescribe high-protein diets to athletes with the same confidence that doctors once prescribed bloodletting for fevers. A football coach might tell his players to eat two or three steaks a day. A bodybuilder might consume a dozen eggs daily. The reasoning was simple and intuitive: more protein equals bigger muscles. The fact that it didn't actually work that way was irrelevant—it felt right, so it must be right.

The consequences were real. Athletes were consuming massive amounts of protein, which their bodies couldn't efficiently use. Excess protein is metabolized and excreted; it doesn't magically become muscle. But athletes didn't know that. They dutifully ate their steaks, their eggs, their meat, believing they were optimizing their performance.

One famous example: Vince Lombardi, the legendary Green Bay Packers coach, would feed his players enormous steaks before games. The logic was that the protein would provide strength and energy. What actually happened was that the athletes were trying to digest a heavy, protein-rich meal while running around on a football field. Their bodies were diverting blood to their digestive systems instead of their muscles. They were probably less efficient athletes for having eaten it.

The Water Myth: Dehydration as Toughness

If the protein obsession was misguided, the approach to hydration was actively dangerous. For most of the twentieth century, coaches believed that drinking water during exercise was counterproductive. The theory was that water would make you sluggish, slow you down, or cause stomach problems. Athletes were actually discouraged from drinking during competition.

This wasn't just bad advice; it was advice that actively harmed performance. Dehydration causes muscle fatigue, reduces aerobic capacity, and impairs cognitive function. An athlete performing while significantly dehydrated is a less effective athlete. But the conventional wisdom was that drinking water was a sign of weakness—real athletes pushed through without it.

The logic was almost a moral argument: toughness meant suffering. If you were thirsty, you didn't drink. You endured. In football, basketball, and other sports, water breaks were rare and often discouraged. Coaches worried that water would make players soft, that it would break their focus or reduce their intensity.

The consequences were sometimes serious. Heat exhaustion and heat stroke weren't rare in mid-twentieth century athletics; they were almost expected. A coach might interpret an athlete's dizziness or confusion as a sign that he needed to tough it out, not that he was dangerously dehydrated. Some athletes collapsed during practice or competition, and the response was often to question their mental toughness rather than their hydration status.

It wasn't until the 1960s and 1970s that sports medicine researchers began seriously studying hydration, and the evidence was overwhelming: athletes needed water. But changing the culture took time. Many coaches resisted the idea well into the 1980s.

Carbohydrates: The Fuel Nobody Understood

Maybe the most significant gap between old and new nutritional science is the understanding of carbohydrates. For most of athletic history, carbohydrates were viewed with suspicion. They were "sugary" and therefore soft, weak, indulgent. Serious athletes ate protein and fat—the "strong" nutrients.

What nobody understood was that carbohydrates are the body's preferred fuel source for high-intensity exercise. Your muscles store energy in the form of glycogen, which is derived from carbohydrates. When you deplete your glycogen stores, you hit a wall—your muscles literally run out of fuel. This is what marathon runners call "hitting the wall," and it happens because they didn't consume enough carbohydrates before or during the race.

But the old approach to athletic nutrition didn't account for this. Athletes might eat a steak the night before a marathon, which provides some energy but not in the form their bodies most efficiently use during endurance activity. They'd start the race with depleted glycogen stores, and their performance would suffer accordingly.

The revolution in carbohydrate loading came in the 1960s and 1970s, when Scandinavian researchers discovered that athletes who consumed high-carbohydrate diets for several days before competition had significantly better endurance performance. The science was clear: carbs were the fuel for athletic performance.

But this flew in the face of decades of conventional wisdom. Athletes and coaches had been taught that carbohydrates were weak, that protein was strong. Changing that belief took time, and many coaches resisted the idea. Some athletes in the 1970s and 1980s felt almost guilty eating pasta before a race—it seemed wrong, contrary to everything they'd been taught about serious training.

The Recovery Revolution

Another concept that barely existed in twentieth-century athletic nutrition was recovery nutrition. The idea that what you eat after exercise matters as much as what you eat before is relatively new. Traditional training philosophy focused almost entirely on what you ate before and during competition. What happened after was ignored.

Now we know that the post-exercise window is crucial. Your muscles are primed to absorb nutrients in the 30 minutes to two hours after intense exercise. Consuming carbohydrates and protein during this window optimizes muscle repair and glycogen replenishment. This is why modern athletes consume chocolate milk, protein shakes, or specialized recovery drinks immediately after competition or intense training.

In the 1960s and 1970s, an athlete would finish a race or a game and... nothing. Maybe they'd get a meal a few hours later, but there was no concept of optimizing the recovery window. They were essentially wasting a crucial opportunity to speed up their adaptation to training.

The Precision Era

Today, athletic nutrition is almost unrecognizable compared to the steak-and-water-deprivation era. Elite athletes work with sports nutritionists who understand the precise macronutrient ratios needed for their specific sport, body type, and training phase. They consume carefully calibrated amounts of carbohydrates, protein, and fat at specific times. They hydrate strategically, not just when thirsty. They consume electrolytes, amino acids, and other specialized nutrients to optimize performance and recovery.

A modern endurance athlete might consume 60-90 grams of carbohydrates per hour during competition, along with electrolytes and fluids. A strength athlete might follow a periodized nutrition plan that varies calorie intake and macronutrient ratios based on their training phase. A team sport athlete might consume specific pre-competition meals designed to optimize energy availability while minimizing digestive discomfort.

This isn't guesswork. It's based on decades of research into human physiology, performance testing, and controlled studies. We know what works because we've measured it, tested it, and refined it.

The Confidence Gap

What's striking about the history of athletic nutrition is how confidently wrong previous generations were. Coaches in the 1960s would prescribe high-protein, low-carbohydrate, dehydrated athletes with absolute certainty. They weren't tentative or uncertain. They were sure. This is what serious athletes ate. This is what champions ate.

And they were wrong. Not partially wrong, but fundamentally misguided about the basic principles of human physiology and athletic performance.

It raises an uncomfortable question: what are we confidently wrong about today? What nutritional or training advice do we think is obviously correct, but will be recognized as misguided in 30 years? We probably won't know until we know.

Were We Ever Here?

The transformation in athletic nutrition from the steak-and-no-water era to the precision carbohydrate-loading, electrolyte-optimized modern approach represents more than just better information. It represents a fundamental shift in how we understand human performance. We went from intuitive, logic-based reasoning (muscles are made of protein, so eat protein) to evidence-based science (here's what actually happens in human physiology).

An athlete from 1960 transported to 2024 would barely recognize the nutritional approach. The food would be different. The timing would be different. The quantities would be different. The entire philosophy would be alien. And yet, the goal is the same: perform at the highest level possible. We're just infinitely better at understanding how to do it.
