Terraform a real ride

I would like to be able to upload a ride that I have done (outdoor) or a ride from Komoot (for example) & the elevation, orientation & distance etc are terraformed. Would be nice to have towns, rivers, bridges etc (for sure nowhere near exact, just indication). It is the elevation, orientation & distance that is important.That way I can train in winter for a ride I want to do in summer etc.
For example, I have a ebike & go on rides 100km & now have a gravel bike & would like to do the same route. Would be great to train on Zwift the same ride.

You cannot upload your outdoor ride in Zwift, but you can make a workout based on the GPX:

Hi Milan, thank you for your feedback. I will definitely try this & create a custom workout this way.
But, I would still like this so I can ‘freeride’ & change gears on my bike to set me up for the good weather. I know it is not currently available, but maybe in future.
