Your Running Watch Measures Data, Not Context
Modern running watches collect an extraordinary amount of data. Heart rate, heart rate variability (HRV), sleep metrics, recovery time, estimated VO₂max, training status and race predictions are all available at the flick of a wrist. The problem isn’t the data itself. It’s the assumption that those numbers tell the whole story. Imagine waking up feeling… Read more

Norwegian double threshold training – what it is, how it works, and who it is for
Norwegian double threshold training, often referred to as double-threshold training, has in recent years become one of the most widely discussed concepts in endurance sport, largely due to the high-profile success of athletes such as Jakob Ingebrigtsen and other leading Norwegian runners. However, the model itself is not new; it was originally developed by runner… Read more

Polarised vs Pyramidal Structure in Running Training: Which Works Best?
A common phenomenon in endurance sports is that many runners spend too much time in the moderate intensity range, sometimes referred to as the “grey zone.” In this case, the workouts are neither light enough to promote recovery nor strenuous enough to stimulate significant adaptation. As a result, Training Intensity Distribution (TID) has become a… Read more

Heat and humidity: How they affect running performance
Running in conditions characterised by high temperature and humidity places significant physiological stress on the body, affecting not only comfort but also performance and safety. A thorough understanding of how heat and humidity influence thermoregulation and endurance capacity allows runners to develop effective strategies for training, competition, and recovery. By integrating evidence-based insights into preparation… Read more

How to Train Your Brain to Tolerate Discomfort
Discomfort is a constant feature of endurance running, particularly as training intensity and performance demands increase. While physical conditioning is essential, research increasingly shows that performance under fatigue is strongly influenced by how the brain responds to sustained effort and unpleasant sensations.

How to Improve Running Economy
Running economy is one of the most powerful, and often misunderstood, determinants of endurance performance. It describes the amount of oxygen your body requires to sustain a given running speed. It helps explain why some runners are consistently faster and fatigue later than others, even when traditional fitness markers appear similar. Two athletes may share… Read more
