Garmin Workout File (.fit) Instructions
There are two .fit files included with each week's workouts. Both files are of the same workout, but the basis of the intervals is different due to potential problems when trying to upload the files to your Garmin device.
The full named file (i.e. "2020 Spring - 90-min - Week 1.fit") was created in TrainingPeaks and includes intervals that are based upon percentage of Functional Threshold Power (FTP).
The abbreviated named file (i.e. "20 Spr Wk1 90min.fit") was created in Garmin Connect and includes intervals that are based upon power zones.
When trying to upload the workout to your device, first try these instructions from Garmin:

Another way to upload the file requires you to connect your device to your computer.
In your device's directory, there is a folder called NewFiles
Copy the .fit file into that folder
After you have copied the file into the folder, disconnect your device from your computer. On your Garmin device, select MENU > TRAINING > WORKOUTS. You should see the workout there.
