The Science of Speed vs Endurance at Different Running Distances
Tread Lightly Running Science PodcastShow Notes
A 5K and a marathon are objectively different distances - but they are also more similar than you think. If you’ve ever wondered why the 5K is technically a long-distance race, or what the difference between training for a mile and a marathon is, this episode is for you! We’ll discuss the metabolic and mechanical differences of the short, middle, and long distances, plus how those theoretical differences translate into training.
