There isn’t a direct feature tin Zwift to import workout files. Therefore I have written a step by step guide to help you through it.
Import a workout file to your Zwift account.
You need to use a PC or MAC to import workouts to your Zwift account. It is not possible to import workouts on yourAndriod or iOS (Apple) device. To start you will need to have the Zwift software installed on your PC or MAC. This can be downloaded from https://zwift.com/uk/download
Once you have installed the Zwift app on to your PC or MAC you are ready. You can now add the workout that has been shared with you to your custom workout library.
Save the workout file set you by email in the downloads folder on your PC or MAC.
Open the downloads folder on your PC or MAC, right click on the workout file and select copy.
Open the Zwift workout folder on your PC or MAC. You will find this by clicking in to your Document folder, then Zwift, then Workouts folder and then finally the folder with the “Numeric Zwift ID”. (File path is Documents\Zwift\Workouts\”Numeric Zwift ID”)
NOTE: If multiple Zwifters access the platform on your device, there will be multiple Numeric Zwift ID folders visible. For assistance with locating your Zwift ID, select Contact Us at the bottom of this page.
Once in the folder above right click and select paste. The custom workout file shared with you will now show in the current folder.
The next time you launch the Zwift app on your PC or MAC you will be able to access the workout you added to the folder. You can access this in the custom workouts menu. These workouts will now sync to your Zwift account and accessible on any device logged in to your Zwift account.
