What you can edit in LeCoach
Open an activity (in the agenda or day view) to:
Rate Feel (1–5) and RPE (effort 1–10)
Change the Sub Type: None, Commute, Race, Warmup or Cooldown — see how pairing and commutes work
Edit the description / add notes
Pair or unpair it with a planned workout
Delete the activity
All edits sync back to Intervals.icu.
Fixing wrong data (elevation, heart rate, cropping, splitting)
Fixes to the recorded data itself are done in Intervals.icu, which has full editing tools: open the activity on intervals.icu to crop or split it, correct elevation, strip a faulty heart-rate track, merge duplicates or re-analyze the file. The corrected result syncs back to LeCoach automatically.
Deleting an activity
Open the activity, press delete and confirm. The activity is removed from LeCoach and Intervals.icu, and any pairing with a planned workout is cleared (the workout returns to 'planned'). Deleting an activity cannot be undone in LeCoach, so if it exists on the original platform (e.g. Garmin) and you re-download old data in Intervals.icu, it can reappear — delete it at the source too if you want it gone permanently.
Duplicates
Duplicates normally don't occur — Intervals.icu de-duplicates activities from multiple platforms. If you do see one, delete the duplicate in Intervals.icu.
