You should be able to upload your .fit file to strava manually.
Also, what system are you running Zwift on? PC, Apple TV, iphone, etc…
Wireless connection? How strong is your connection? Maybe try a wired connection if wireless is weak/poor signal.
Make sure everything is updated to the latest version of Zwift.
The last I knew Zwift doesn’t have the functionality to upload lost rides so if you ended a ride and something failed and crashed, the ride is lost forever within Zwift. You should contact support to see if anything has changed or if they can help in anyway.
This is most commonly caused by a connection issue between the device running Zwift and the Zwift Servers that results in not being able to save the ride to all save locations. The rides may be able to be recovered via your dashboard at my.zwift.com, or by finding the .fit file in your computers storage system. Once you have the .fit file you can upload the ride to strava or other 3rd parties manually. Stats such as distance, elevations, experiance, and drops can’t be credited to the account however, due to technical limitations. I hope this helped everyone with this type of issue!
Happened to me too recently along with some other weird issues. It may not be wifi related, an Zwift used to handle intermittent disconnects and reconnect ok but I’m not sure anymore. The official Zwift suggestion of relying on 3rd party services rather than Zwift itself for stats is not helpful if you only use Zwift.
Signal strength is 100%. I even brought the laptop in next to the modem to save the ride and the same thing happened. The window crashed, closed and brought me back to my desktop. Super frustrating.
Did you ever get any resolution to this, David? I had the same exact thing happen to me last night after the Prudential Fondo. I have a hard time accepting Zwift’s answer that they cannot recover my file when both the Ride Report shows all the extra miles I completed…and, as you said, it shows up in Zwiftpower just fine as well! So I don’t understand why only 11 miles of my ride was sent over to Strava!
Sorry for the late reply. I did open a ticket with Zwift and they mentioned they could help me get credit for the ride in terms of unlockables, it was one of the MAAP stages so they could help me get credit for the jersey, but they couldn’t do anything to get credit for the ride itself (such as capturing distance and elevation in zwift itself). A bit disappointing because I’m low level and don’t want to lose rides.
I searched around the forums here and elsewhere and one post was saying to always select “stay here” after a ride completes, if it’s an event. I’ve tried this but I’ve still lost at least one ride doing that. I noticed in a few rides I lost credit for that I finished the ride, took a quick break, then returned to do a cool down and complete the ride. I’m having better luck completing the ride and then doing a cool down separate if I want. Anyway, not sure either of these things really help just sharing. Really wish Zwift would come up with a way to upload the file for credit like other sites do.
