Combi vo2max-threshold-tempo training
4 x 1min at 80% FTP (1min recovery at 50% FTP); then 4min VO2max at 110% FTP and 3x 4min Threshold at 95% FTP, framed by a warm-up and cool-down.
This training improves your aerobic ceiling, helping you go harder for longer.
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.
