First, we have shown that on a level and hard course, the ECOR is typically 0.98 kJ/kg/km. Of course,

Some 2,5 month ago Hans ran the 15 km 7HillsRun in 59:34 and with an average power of 244 Watt (or 4,21 Watt/kg, which is actually a better parameter). We analyzed the results in a paper (see https://blog.stryd.com/2019/12/17/an-in-depth-analysis-of-a-15k-race-seven-hills-run/ [https:

The performance lab of a Sports Medical Center offers various tests. In this paper we elaborate the testing of the aerobic system of a runner on a treadmill. To test the aerobic system the load is step-by-step increased by increasing the speed of the treadmill. Such a test goes beyond

The Seven Hills Run is an annual 15 km road running race held in Nijmegen, the Netherlands (https://en.wikipedia.org/wiki/Zevenheuvelenloop). It has grown into one of the largest road races in the Netherlands with 40,000 participants. In the 2010 edition, Leonard Komon improved the official 15

In our book The Secret Of Running (www.thesecretofrunning.com [https://blog.stryd.com/2019/12/06/what-are-the-human-limits-of-running-power/www.thesecretofrunning.com] ), we have described our unified theory for the performance in running and cycling. Our running model is based on the premise that the power produced by the “human engine”

Traditionally, runners use pace as a surrogate for their effort during racing. Theoretically, the effort during running is defined by the power of the ‘human engine’. In our book “The Secret of Running" (www.thesecretofrunning.com [https://blog.stryd.com/2019/12/06/why-is-racing-with-power-superior-to-racing-at-pace/www.thesecretofrunning.com] ) we have

Many books and papers have been written on training plans, including such aspects as training goals, training modes, training paces and training mileage. Running with power provides us with new tools to optimize the training in real time and on a daily basis. In this paper we will discuss the

The holy grail of distance running has always been to use less energy and oxygen at a certain speed. The recent breakthrough of power meters raises the question whether we can use the new running metrics to learn how to run smarter, more economical and faster? In recent running research,
