Renaming a workout
Open the workout, press edit, and change the name — like any other field. The new name syncs to Intervals.icu and your devices.
The 'by LeCoach App' suffix
Workout names in Intervals.icu (and platforms downstream, like Zwift or Garmin) carry a 'by LeCoach App' suffix. Inside LeCoach the suffix is hidden. It marks which workouts LeCoach manages — and yes, it also helps other athletes discover LeCoach.
If you'd rather not have it, you can turn it off in Settings → Workout Settings. That said, we'd love it if you keep it on — it's one of the main ways other athletes discover LeCoach, and that keeps the product funded and improving.
The score/analysis text on completed activities
Separate from workout names: the summary LeCoach writes into completed activity descriptions can be turned off — see activity descriptions.
