On mobile, opening a downloaded .fit file with Garmin Connect can incorrectly import it as a route instead of a workout. Sending it to Intervals.icu instead avoids that — Intervals.icu pushes it on to your connected Garmin or Wahoo device automatically.

Download files (.fit / .zwo)

The .fit file works on Garmin/Wahoo devices. The .zwo file is the original Zwift format — use it to import this workout directly into Intervals.icu (drag it onto your workout library), Zwift, or TrainingPeaks. Both use power targets as a percentage of FTP, applied automatically based on the FTP set in that app or device — the field above only adjusts the watt numbers shown on this page.
