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 refreshed, well-rested and ready to train. Then you check your watch. It reports a low HRV, suggests you’re not fully recovered and recommends an easy session instead. Do you trust the watch, or your own body? And if you go ahead with a hard workout anyway, have you really compromised your progress?

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 and researcher Marius Bakken, who began refining a structured approach to threshold-based training.

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 central topic of discussion in endurance training. While there is strong consensus on the benefits of polarised and pyramidal training, there is no single, superior model.

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 the same VO₂ max, yet the runner who moves more efficiently will cover more distance at the same physiological cost. Improving running economy, therefore, is not just about fitness, but also about how effectively your body converts energy into forward motion.

Double Running Days: When, for Whom, and How

For many endurance athletes, the concept of running twice in one day is both intriguing and intimidating. Double running days — often called “doubles” — can be an effective way to increase training volume, improve physiological efficiency, and develop resilience. But, as with any advanced training tool, they require careful planning and a clear purpose.

The Role of Biomechanics in Running: How Proper Technique Enhances Performance and Reduces Injury Risk

Collaboration with Ochy – running biomechanics app

Biomechanics goes together with physiology, combining different areas. Running biomechanics have been studied a lot, but studies have not been able to demonstrate the superiority of one running technique over others. There are as many running styles as there are runners. There are as many differences among professionals as there are among regular runners. One technique is not more optimal or more prone to injury than others.

How Cycling Can Improve Your Running Performance.

Collaboration with Bikemap.

Combining different forms of exercise can be beneficial in terms of improving running performance. Running and cycling are different activities with their own characteristics. One of the biggest differences between cycling and running is the impact force. Cycling doesn’t have the regular pounding of the legs, but incorporating cycling into your training can still improve your running performance and bring many benefits to your training.
