If you have a Suunto Ambit 3 Run, you can only pair Stryd as a foot pod and use Stryd for pace and distance on the watch. You can upload your power data from Stryd with your phone post-run.

The Suunto Ambit 2 watch uses ANT+ to connect to Stryd. The Ambit 3 and most other Suunto watches use Bluetooth to connect to Stryd. This creates some subtle differences between Ambit 2 and other watches.

Stryd can connect to multiple ANT devices at once. This means that with the Ambit 2, Stryd can be paired as a foot pod AND power pod. This allows users to get power and pace from Stryd if paired as a power pod and foot pod.

Stryd will not get activated by the watch itself. When you go for a run, Stryd will detect the motion and start recording and reporting power. When power hiking with Stryd, Stryd may not get activated at all, or the recording may stop when switching from running to power hiking.

Stryd can only support one Bluetooth connection. This means that with the Ambit 3, Stryd can only be paired once. Users will have to choose between a power pod (to get power on the watch) or a foot pod (to get pace and distance from Stryd).

Other Suunto watches such as Suunto Spartan, Suunto 9, etc. have special accommodations for Stryd. Suunto allows Stryd to be paired as a foot pod and still show power as well. So, users can get pace, distance, and power from Stryd.
