How is the Fitness/Fatigue graph developed?

The Fitness/Fatigue graph allows you to monitor the impact of your training load on your physical condition, your fatigue, your fitness, and your level. 

By analysing your scheduled sessions, you can plan your peak fitness levels or manage the phases of poor performance during your preparation. 

The four curves in the graph are as follows:

  • Yellow curve: physical condition linked to your training load over time, with a positive impact in the long term (42 days).
  • Orange curve: Fatigue, also related to your training load, with a relatively short negative impact (7 days).
  • Red curve: Your fitness, equal to the difference between your physical condition and your fatigue.
  • Blue curve: your level, established from your physical condition (yellow curve) and your power capacity (FTP).
