Any help from the mods appreciated for my problem below… Thanks! Hi. Just joined the site and trying to upload my exercise data from Polar Flow. Followed the instructions (or at least thought I did!) and got an email from Intervals to say ‘Polar data import complete’ but also that ‘0 activities cr…

I never heard back from anyone on this issue. In the end I went via the Strava import route, but I didn’t become a Strava user until 2020 so I ‘lost’ data (i.e. was unable to upload all the Polar history) that isn’t captured by icu. I also posted a separate question about uploading single exercise f…

I’ve just tried it, and it worked for me. [image] But maybe there is something special in your activities or zip file (?) In this case only David could help. Edit: as a workaround you could download your historical activities to Dropbox and import these activities with Dropbox.

Do you mean the Zip file or the individual files? Why does it work from Dropbox but not directly?

I mean you could download the zip, unzip the file and put your historical activities into a folder. You can link the folder in the settings and the activities should be imported. This works flawless for me. This way only activities will be parsed.

Still no joy and I’m at a loss. Here’s what I’m doing now: -Dropbox linked in connections -polar historical zip file in Dropbox -extracted zip in Dropbox with all the activities and whatever else is in polar zip under one parent folder -importing history via polar connection in intervals using …

You still can try to import Polar zip file, but I think, there is something “special” in it, and that’s why it may be that it stops parsing before importing any activity. If you want to do it that way, send @david or @eva an DM with the link, so that they could have a look and fix it. For dropbox -…

Ahhh. Interesting. Nearly all of the files are json files, not fit or tcx or gpx.

Never occurred to me that polar would be sending files in wrong format. I used Polar JSON to FIT Converter - Tredict to convert all of them to fit in a single batch. The Polar connection still would not load them, but the dropbox connection said it is loading all 735. Assume it will take a few fo…

We have updated the Polar history import. The file format changed completely. Please give it a try if it previously failed for you.

I cannot get my Polar data into Intervals. I have tried two ways - In Intervals, navigate to settings - connections - click “Import all Polar Data” and follow the steps. I download the data and save it as a zip file on my laptop. The Intervals website asks for a http or https link and does not …
