Switching platforms usually means starting with an empty calendar, and years of training suddenly become a screenshot in an old app. The Strava import exists so that does not happen.
How it works
Strava offers a complete export of your account, which they call the Bulk Export. You request it there, they mail you a ZIP, and you upload that ZIP in Coachbox. We process it in the background into workouts in your calendar.
The import only touches your activity data. The rest of what Strava puts in that export is left alone.
Duplicates are handled
If a workout is already in Coachbox, whether from another platform or an earlier upload, the import recognises it and skips it. The summary at the end tells you how many landed and how many were skipped.
Two things it does not do
It does not bring your training zones. Those are yours to set, or your coach’s, and inheriting a stale threshold from another platform would do more harm than good.
And it is not a live connection. This is a one-time move of your history. If you also want new Strava activities to keep flowing in, that is a separate thing from this import.
Coming from TrainingPeaks instead? Their export works differently, so follow the TrainingPeaks import.
