Need help with combining two .fit files which seems corrupt

e97b82909e83430191bfebff17e67e8e 8 months ago

This morning I ran a half marathon and unfortunately made two different workouts for this.

I tried combining the two files in fitfiletools but the output seems corrupt and I can't upload it to Connect.

Can someone please help me out and combine the two files in such a way that I can import one file into Connect.

Thanks in advance!

Hi, I have a personal project to combine fit files that can be found here: https://github.com/muktihari/fit/tree/master/cmd/fitactivity.

Download the CLI program based on your OS (or build it from the source code), then run these following command in terminal:

fitactivity --combine -o result.fit 2024-03-23-09-01-58.fit 2024-03-23-09-43-48.fit

Just test it by uploading to Connect and it works, I can't upload file here so it seems you need to do it yourself.

Hi e97b82909e83430191bfebff17e67e8e. My previous program has bug making it unable to upload to GC, it will be fixed on next release (you can build from source code from time being). And since now I know how to upload the file, here is the resulting file.

muktihari's CLI program sounds quick, easy and best for your purpose.

But, in case you need more visibility and specific corrections.

Another tool which can combine two corrupt FIT files and many other things is the FIT File Repair Tool here:

https://www.fitfilerepairtool.info/

This is an Access database program in which you can even make corrections manually if you need to.

When simple solutions fail, I usually resort to this tool.
