Why do my fitness and fatigue numbers change the next day
I checked my numbers after a ride, fitness was 91, fatigue was 121. The following day, I checked my numbers after another workout, and the values from the previous day had changed. Now they are fitness 86 and fatigue 90. Why did the values drop retroactively?
I took screenshots to show the discrepancy.
My guess: You have a scheduled workout on that day and then complete an activity afterward. However, since the load doesn’t match (e.g., because you’re doing longer or shorter activities), they don’t “align.” As a result, your daily load is the sum from the completed activity plus the scheduled workout, because intervals treat the workout as not completed if the load differ too much. The next day, the “uncompleted” workout is marked as not completed, and the workout load is no longer counted.
If you notice a mismatched workout, you can drag and drop it onto the activity.
