Send workouts through Intervals.icu
Updated November 1, 2026
Shape puts your plan on your Intervals.icu calendar, and Intervals.icu passes it on to your device.
Turn it on
Go to Settings → Connections, open Intervals.icu and turn on Send planned workouts. It’s off by default.
What can receive them
- COROS, Suunto, Huawei and Amazfit watches, and Zwift.
- Not Polar watches.
Leave it off with a Garmin or Wahoo
Shape already sends to those directly, so turning this on would put every workout there twice.
If you change a workout
Edit a planned workout in Shape and it updates on your Intervals.icu calendar automatically. Delete it and it’s removed there too. Sync your device to get the change.
