The Science of Marathon Running

Why does the marathon push the human body to its absolute limits? And why do some people seem built to keep going when everyone else hits the wall? On this week’s podcast, Professor Luke O’Neill takes a biochemical deep dive into marathon running, sparked by a listener’s request. The modern marathon may trace its roots back to Ancient Greece, but what happens inside the body during those 26.2 miles is a very modern scientific story — one that turns runners into walking, sweating demonstrations of bioenergetics. Luke explains how the body powers long-distance running by converting energy rather than creating it, moving between carbohydrates and fats to keep muscles firing. ATP — the energy currency of life — sits at the heart of the process, with phosphocreatine, glycolysis and oxygen all playing starring roles. When carbohydrate stores finally run dry, runners hit the infamous “wall”, a moment when the body is forced to switch fuel sources, and everything suddenly feels much harder. The podcast also looks at how training physically reshapes marathon runners over time: denser networks of capillaries in muscles, powerful hearts with remarkably low resting heart rates, and lungs capable of shifting huge volumes of oxygen. Luke explores why elite runners can seemingly run a marathon at will. There’s science behind the mental side too. Endorphins and the so-called “runners high” can lift mood for days, while visualisation plays a key role in endurance. Luke even dips into the Guinness Book of World Records to uncover astonishing marathon facts, including runners in their 90s and some jaw-dropping physiological extremes. Along the way, Luke admits he’s never run a marathon himself — but from a biochemist’s point of view, few sports are more revealing of how the human body really works.

78. The Science of Dopamine

It's called the "motivation molecule" and it is a central factor why we do what we do every day. This week Luke explores the science of dopamine, explains why certain activities cause it to spike and fall, and how we can better handle it to avoid dramatic swings in our dopamine levels, and coach our bodies to better handle it.

74. The Science of Dinosaurs

We may think we know it all about the dinosaurs, and their end, but new discoveries continue to emerge and this week Luke delves into all that is new in the prehistoric world – including the “ultimate dinosaur drumstick” and what this one special bone is telling us. We learn about the tiny shrew which arrived after the dinosaurs, and which we evolved from and how aerosols and dust were the ultimate end for the dinosaurs. It is a story of pure chance and random events that altered our earth entirely, and Luke is only too happy to dive in. Listen and subscribe to Show Me the Science on Apple Podcasts and Spotify.

83. The Science of Coffee

It can feel like a lifeline in the morning, or when you need a boost during a long day, but could our daily coffee be doing far more for us that just that caffeine kick? Luke explores the findings of a major new study that has made some startling findings about the powers of the coffee bean, and how just two cups a day can have a staggering impact on your life, for the better. There’s also good news for those people who enjoy a late night coffee, but avoid it for fear it might disrupt sleep.
