What is TSS (Training Stress Score)?

TSS (Training Stress Score) is a method of quantifying the intensity of a cyclist's training rides. It is comprised of both the duration and the intensity of the ride and is used to measure the overall load of a training program. TSS is measured on a scale of 0 to 100 and is calculated by multiplying the intensity of the ride (measured in normalized power) by the duration of the ride (in hours).

For example, a two hour ride with an intensity of 200 normalized power would have a TSS of 400 (200 x 2). Generally, a TSS of 200 or more is considered a high-intensity ride. The higher the TSS score, the more stress is being put on the cyclist's body.

TSS is used by cyclists to track their performance over time and to measure their progress. By monitoring TSS over a period of time, cyclists can adjust their training program to ensure they are pushing themselves enough, but not over-training. It is also used to measure the intensity of a race or event.

TSS is a useful tool for cyclists of all levels, from beginner to professional. It can help cyclists track their performance and adjust their training program accordingly.


Exploring the Origins of Cycling Term 'TSS (Training Stress Score)'

The cycling term 'Training Stress Score' (TSS) was first coined in the early 2000s by Dr. Andrew Coggan and Hunter Allen, two cycling coaches in the United States. The term was used to measure the intensity of a rider's training session. It was developed as a reliable way to measure the physiological stress of a workout, which was seen as a better indicator of fitness than pure mileage.

TSS was designed to measure the overall intensity of a ride, taking into account both the duration and intensity of the effort. It was based on the idea that the greatest gains in fitness come from training at the highest intensity level possible. The TSS system assigns a numerical value to each training session, with higher values indicating more intense workouts. This system allowed riders to measure their training load over time, making it easier to track progress and adjust their training plan accordingly.

TSS has become an important tool for cyclists and coaches alike, as it provides a reliable way to measure the intensity of a workout. It is widely used by professional athletes and amateur riders alike, helping them to maximize their training efforts and reach their performance goals.
