Just upload the two (or more) files to the tool on the main Combine GPS Files for Strava page. You can interlace Heart Rate, cadence, power, and/or temperature data from one device with the GPS tracks from another device. You would like to have your heart rate data on Strava along with your map. Let's say you already have a heart rate monitor, and you record your GPS track on your phone. How to interlace Heart Rate and/or power data with position dataĪnother common use for the tool is to merge Heart Rate data from one device with the Position Data from a GPS.

In this case, you will want to select all of the 'Streams' (notice the checkboxes next to Position, Elevation, and Heart Rate in the table below? Once you send the combined file to Strava, your ride will be full-length! In the image above, the horizonal red and orange bars represent the duration / time of your loaded GPS files.

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.
