First of all you can download your Log File on my.zwift.com. And second i don’t think a Log File on Zwift will be sufficient. They are probably requesting real life data, out door performances that back your effort on Zwift.
Hey Andre just a heads up, you can’t download your log file from my.zwift.com but you can download your .fit files from your dashboard. I’ve attached a photo to show where you can click “download”.
Unfortunately right now there isn’t a way for you to gather your log files from your Apple TV version of Zwift.
