Glossary: Performance condition
Performance condition is a metric provided by Garmin that analyzes pace, heart rate and heart rate variability within the first 20 minutes of an activity to make a real-time assessment of your ability to perform compared to your current fitness level. Performance condition values range from +20 to -20, whereby positive values mean that you are rested and in shape for a good and intense workout.
Runalyze will import performance condition from fit files if available.
