Rungap for iOS exports GPS data as JSON file in the free version. This script converts it to GPX. Tested with python3.6. Might need to install required modules. Simply place either the metadata and data json files, or the complete zip file in the same directoryas the script and run it. Warning: Does barely any error checking

thanks for this. I tried this but i cannot get this to work. I think now the json files are not rungap and metadata but instead *nike.json and *metadata.json.
other than that "laps" is in metadata_data not data
after changing these, I still get stuck at "points" which cannot be found

Traceback (most recent call last):
File "C:\Users\Desktop\test\RungabGPX.py", line 72, in
print("Found " + str(len(metadata_data["laps"][0]["points"])) + " track points")
KeyError: 'points'

I tried deleting ["points"] and then it runs. it says it finds 6 track points. However strava reports that the files is empty when trying to import it. Indeed, checking the created file.. it does not have much in it.
any ideas?

Thanks for the script. saved me 3.99$.
I got it to run with a few changes :
13: value = unicode(value) #from str
63: ElementTree.SubElement(metadata, "time").text = metadata_data["startTime"]["time"] #removed timezone
76: ElementTree.SubElement(trkpt, "time").text = datetime.fromtimestamp(point["time"]).isoformat() #removed timezone

Thanks, worked for me without any modifications. Python 3.7.5, RunGap for iOS 2.39.

Hi.
I've tried both the original file as well as the modifications from curlyjordi. I have three files in a zip folder from my exported nike run via rungap. Two are JSON files and the other is a png of the map. I've unzipped the folder and put the script in the same folder. Running the script I get the error:

Found metadata files
['2019-12-20_05-17-13_nk_d0301bdd-5c63-4466-97f3-db5fa6bdfcce.metadata.json']
Found data files
[]
Error, number of metadata files does not match number of datafiles!

The other file is called "2019-12-20_05-17-13_nk_d0301bdd-5c63-4466-97f3-db5fa6bdfcce.nike.json"
Can anyone enlighten me please?
Thanks so much,
John

The other file is called "2019-12-20_05-17-13_nk_d0301bdd-5c63-4466-97f3-db5fa6bdfcce.nike.json"

Oh, try renaming that to "2019-12-20_05-17-13_nk_d0301bdd-5c63-4466-97f3-db5fa6bdfcce.rungap.json" (replace the "nike" with "rungap"). I did not anticipate the field being named differently than rung's usual file names!

Thanks. That works better!
Using your original script I get

Absolutely appreciate your help here!

Looks like rungap has changed their file format, give me a coupe minutes!

Looks like rungap has changed their file format, give me a coupe minutes!

Thank you! Would you like me to send you the files?

@jcbigears Yeah, that would help! The regular one still works, might be a difference with the nike files

@jcbigears Alright, I updated the gist. Turns out the .nike files have a different format

I tried.
I failed.
Sad face emoji.

I changed line 13: value = unicode(value)
and it worked perfectly!!!!!!
Thank you @huattedonmyarm!

Hi! It's very nice script. Thank you for that. I've noticed that it doesn't pass heart rate data to .gpx. I've tried to make some changes on my own but got stuck. Problem is that number of gps (lat|lon|ele) points does not match number of heart rate points. And I don't know how to properly map it to each other. Can you add it to your script or give me some ideas how to do that?

GPX data is (essentially) a list of track points, which contain data such as lat/lon and even heart rate. So you could do either of these I guess: • Add all heart rate points as their own trackpoints without setting the GPS data for these. • Add the last read heart rate to each GPS trackpoint (and throw away the other hr readings) • Add the average heart rate since the last GPS trackpoint to every trackpoint

I'm a noob with this programming stuff.

The script first says it cannot find module pytz, if i remove that from the code:
When I run the script the newly created "__MACOSX" folder contains only blank folders with no content.

you'll need to install the dependencies. Run pip install pytz and try again with the original file

Hello

I have installed pytz but the newly created __MACOSX folder contains empty folders

Can you manually unzip the file generated by rungap and tell me what’s in it? Am 2. Mai 2020, 06:22 +0200 schrieb SpicyStingray :

Unzipped it manually then placed every file into one big folder, worked perfectly, thanks

Ah, I think I know what the issue was. Should work with the zip file now too
