What this format is
A few older platforms still want TCX. Heart rate and cadence in Garmin’s GPX extension are copied into TCX trackpoints. Power goes into the activity extension.
How to get the file
- From Garmin Connect
- 1. Activity → ⋯ → Export as GPX, then convert here if you need TCX.
- From Strava
- 1. Activity → wrench → Export GPX.
- 2. Drop it here for a TCX copy.
