FAQ: FTP & Zone Settings
How to setup FTP History?
FTP in Intervals.icu is copied to each activity. If you change FTP today, old activities are not automatically rewritten.
Best practice:
- Open Activity List and show the FTP column.
- Set/correct FTP values for the relevant date ranges.
- If many activities are affected, use bulk edit on the activity list view (
Edit > Edit).

Why is my Heartrate clipped?
Usually this is caused by max HR / HR zone settings that are too low (or historically inconsistent).
Fix:
- Update max HR and HR zones.
- Apply the correct values to the relevant time period.

Why is my Power clipped?
Most often power clipping is caused by spike settings: values are detected as unrealistic spikes relative to current thresholds.
Fix:
- Set a realistic FTP (also check sport-specific FTP).
- Increase power spike threshold if genuine peaks are being cut.
- Re-analyze affected activities.

Why does eFTP look inconsistent, wrong, or not update the way I expect?
What to do: Treat eFTP as a suggestion, not an automatic truth. If the estimate looks wrong, do not accept it. Your previous FTP stays in place until you explicitly accept a new value.
