i have never had trouble downloading partial saves from the fit files and when i do i get the full ride upload it to your strava from my documents/zwift/activities.
I’ve had this before. Zwift saves the fit file locally (in the same place zwift is installed) before uploading. If you find it there it should upload to Strava etc fine.
You ride only goes on zwift.com at the end, like Strava, so the drop screws that over too.
Hi I know this thread is old. I too had issue with a partial workout. Zwift only saw two miles of the workout. I was able to find the local file and recover the entire workout. I searched computer for *.fit files and located the workout. When uploaded to Strava, it contained entire workout. Hope this helps someone else
Hi, one more suggestion. If you download the FIT file from Zwift or find the local copy and it is corrupt it is worth trying Fit File Repair Tool (see http://fitfilerepairtool.info/). I use this software frequently to fix corrupted FIT files from my Garmin and it works with files generated by Zwift also.
