What is the coach’s feedback / debriefing based on?

Analyzing a running unit is difficult. In fact, many factors can distort the analysis, first of all the quality of the data.

The most reliable method is to analyze your own feelings, which you stated at the end of the session.

What is taken into account today

It is scientifically proven that it is useful to take into account the runner’s feeling of effort, and this is exactly what we ask for after we have linked the activities to the planned session. The debriefing of the training session is therefore based on this feeling by comparing the expected feeling of effort with the one stated by the runner. This blog post explains the evaluation of perceived exertion.

For a 50-minute training session with 6 straights, you should expect an RPE value of around 5/10 (half value), because even if the endurance is easy (RPE between 1 and 3/10), the small accelerations at the end add an extra degree of difficulty.

For other splits, the RPE should be between 6 and 10/10, depending on the type of split: short (MAS or 5 km pace) or long (10 km, threshold, half or marathon pace).

The overall data can also be used to calculate the training load, which we take into account when creating your program over several weeks.

Why is it difficult to analyze numbers?

Numbers must be analyzed in context

GPS accuracy is at best 1% or 10 meters per kilometer or 2 to 4 seconds per kilometer for runners.

Moreover, the heart rate, which is usually measured with an optical sensor on the wrist, is often not very accurate, even with high-quality watches.

In addition to these measurement-related factors, external interference in particular can affect performance:

The weather
The night
The surroundings: will I be stopped at an intersection or by other road users?

Factors specific to the runner can also influence performance

Degree of fatigue
Stress levels in private and professional life
Biomechanical problems in the event of an injury

We can refer to the weather, the time of day or other factors, but it's still very complicated to analyze a session without taking these different factors into account.

Training pace is mainly based on your past times and your achieved times. Competitions are often more reliable to analyze because the above factors are often optimized on race day: unobstructed course, optimal fitness level, race excitement….

We're working to give you more accurate feedback on your performance based on the above data.
