Remember this guy at the Red Hook crit? This is how I feel when my race drops on Zwift. Luckily my bike is strapped to a heavy trainer…

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 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 No matter what happens with that 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 to get full “credit” for your ride within Zwift–meaning the ride in question will probably show as a “partial” on 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 to yourself. Here’s how it works:

Step 1: Tap the ZWIFT logo 3x

Step 2: select your ride from the list and click “OK”

Step 3: send the email! (Don’t send it to me–send it to yourself!)

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 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!
