The Waterrower for example has the manufacture id 118 so it exist but not yet used. But also a lot of other things can be stored in that file. An example is each sport has an dedicated number. This new file is a binary file which has all the information needed. Rowing machine, Smartscales and the list goes on. Which has a lot more information and can be used for a lot of fitness IoT devices.

In order to achiv to store a lot of data on small smartwatch, garmin decide to introduce a new format which is called the FIT format. Garmin begun developing smartwatches and switched from being a gps for cars manufacture to a fitness gadget manufacture. This file format has only 3 categories for sport : ( Running, Bike and Others). In the early days of data gathering for sport activities, Garmin developed the program Garmin Training Center link and along with the program the exchange file Training Center XML (TCX) has been developed. But there is a limitation.īut first let's talk background for garmin's file formats: This file can then be uploaded to garmin connect to track progress or Strava or to many more. Limitation: I had to calculate the amount of calories with a different forumla as the exported tcx file gives usĪre you using the Waterrower with the Android app Coxswain and also use Garmin connect? If yes then this python scriptĬoxswain can export a workout to the Garmin format TCX. Import TCX file from coxswain and convert to garmin FIT formatĬreate 500m splits aka in the Garmin world as 'Laps'Īdd the ability to add User Profile if you haven't a Garmin productĪdd heart rate zones if you haven't a Garmin product It can hold much more detail of meta data, for examples a lot of different sports and is it much smaller in storage and processing speed.Project Coxswain exports to FIT converterĬonvert garmin TCX export file from Coxswain android app (Waterrower) to a garmin FIT file. The conversion to FIT is done almost lossless, except the zones distribution, which isn't convertible in a meaningful way to the FIT context.įrom a technical stand point Garmin FIT is preferable in many ways over TCX or even GPX.

The by Polar exported JSON is actually very detailed and no information is missing by the export as far as I can tell. So with the converter you can easily add your older Polar workouts to your favorite platform like Strava, TrainingPeaks, Runalyze, etc. Most of the modern training platforms are accepting. I have written a Polar JSON to Garmin FIT converter tool to convert all my Polar training history from the Polar Flow export into an widely used an state-of-the-art (more or less, hehe) format.
