If your Zwifting is interrupted by a power outage, computer reboot, or Internet problems you may “lose” your current ride without being able to save it properly.
Sometimes, everything may seem to be working fine, but after your session the saved ride never shows up on Strava, and signing into Zwift.com shows your ride as a “partial ride.” This indicates Internet connection issues at some point in your ride which prevented your device from sending ride data up to Zwift’s servers.
Take heart–all is not lost! Lucky for us, Zwift saves your activities on your computer/device as well as sending the data to Zwift.com. No matter what happens with that Zwift.com connection, you can always retrieve your local file and upload it to Strava or any other service.
At this time you cannot upload the file from your computer to Zwift.com to get full “credit” for your ride within Zwift–meaning the ride in question will probably show as a “partial” on Zwift.com forever.
Retrieve Your Ride on Zwift for PC/Mac
Each of your rides is saved on your computer at %USER%\Documents\Zwift\Activities\ as an industry-standard .fit file. Just find the ride in question and upload it to Strava or any other service.
Retrieve Your Ride on Zwift for iOS
There’s a hidden feature on Zwift for iOS (iPhone and iPad) which lets you easily access your list of ride files and send them via email. Here’s how it works:
Fix Uploading Errors
If you get an error when attempting to upload your .fit file to Strava or another service, it could be that the file was corrupted when Zwift suddenly closed (for a power outage, etc). In that case, head over to fitfiletools.com and fix it using their tools (“Corrupt Time Fixer” is often the solution).
It can be a real bummer to finish a Zwift ride only to realize it didn’t save properly. Happily, following the simple steps above will let you post your ride to Strava or other services. As we know… if it isn’t on Strava, it didn’t happen!
