Hello Internet friends,
I was running a marathon recently, and somehow managed to stop and save my activity while reaching for my bag. So I ended up tracking two activities for a marathon.
Now, I was merging those two files to get the delicious marathon badge, but this is not working. I use fitfiletools to merge files (it works), and then I use it to add the Garmin device, so it can earn the badge (this does not work).
Any tips on what can be wrong? I get a mysterious "An error occurred with your upload. Please try again.", without any further info.
Thanks!
