What is the source of pace and distance when merging Suunto/Polar data with Stryd data?

The Stryd platform offers the ability to merge watch data from Polar and Suunto with data stored on Stryd (by doing an offline sync). This allows Suunto/Polar users to get all the advanced metrics in one data set, even though the watches do not record LSS, VOSC, and other advanced data.

Here is a break down on the source of each metric you see in PowerCenter:


| Stryd



















Form Power




Air Power


Please note: The merge algorithm favors watch data for pace and distance. Hence, if the watch recorded distance is different than Stryd distance (because the watch was set up to use GPS for pace/distance or the watch applies a calibration factor to the Stryd data), the watch distance/pace will be stored whereas the Stryd pace/distance information will be ignored.

How can I improve merging Suunto data with Stryd data?

The order of loading your data into our platform makes a difference. Next time when you try to merge your data, can you try the following:

  1. Sync the Suunto/Polar watch data first. Wait for the data to appear in PowerCenter or in the Stryd app on your phone.

  2. Only after you see the data from Polar in PowerCenter, do the offline sync.

  3. ​Please share your findings (good and bad) with us. If your data does not merge, Stryd can help merge your data.

Stryd Interval Workouts with Suunto 9

Suunto 9 has a basic interval function that could be used when running with a Stryd pod. The interval function is basic but may be helpful when doing a structured Stryd workout. This article is to make sure that your Suunto data can properly merge with the Stryd workout in your calendar.

The Suunto interval feature allows you to select the interval duration or distance, a rest duration or distance, and the number of repetitions. Suunto does now allow you to set a power target for the interval, but you can set up intensity zones on your Suunto and train by power zone.

You can use the Suunto interval functionality for any Stryd workout that has an equivalent structure like interval training (i.e. same duration for intense segments, same duration for rest segments).

Details on how to set up the Suunto watch for interval training:

In addition to enabling the interval feature, you must disable auto-laps on your watch.

When you start your workout, you can do a warmup at a duration/distance of your choice. Once warmed up, you start the interval training.

Special action: Suunto does not mark the start of the first interval as a lap. This means that the Suunto data will not align well when merging with the planned workout as the Stryd system relies on lap information. Do the following to get the correct alignment between workout and run data:

  1. Do your warm-up

  2. Start the intervals on your Suunto

  3. Immediately hit the Suunto lap button (only for the first segment of the interval training)

  4. Execute the interval training, you can either memorize the power target or use the Suunto intensity zones.

  5. Cooldown as normal, end your run and your data will align correctly when uploaded into the Stryd ecosystem.

Stryd power drops when running with Suunto watches

If you notice power drops when looking at your data in PowerCenter or the Stryd mobile app, you can stop automatically importing your data from the Suunto app and upload the Stryd data directly with the Stryd app on your mobile device. You will get all the Stryd metrics but miss out on HR and GPS data.

Suunto Ambit 3

You may see many power drops that each last just a second when you look at your data in PowerCenter. These drops are not present when running with the watch or in the Suunto app (data below from Suunto Ambit 3 vertical without HR monitor):


Our own testing has shown that disabling GPS improves the Ambit watch performance (Ambit 3 Vertical without HR monitor):


This is a Suunto issue, the watch simply does not record any data during that one second:


You can see that there is no power, no speed, no altitude, no temperature, or run cadence. You will not see this drop in the Suunto App as Suunto will filter out these points in their graphs whereas Stryd simply plots each point.

Suunto 5/9 or Spartan

You may see power drops for just a second when you look at your data in PowerCenter. Below is an example, at 2:00 minutes power and pace are 0.


This is a problem with the watch. At that point, the Suunto watch is not saving any data into the FIT file. Here is the data from the FIT file (screenshot from Golden Cheetah):


You can see that there is no power, no speed, no altitude, no temperature, or run cadence. You will not see this drop in the Suunto App as Suunto will omit these points in their graphs whereas Stryd simply plots each point.

How do I setup the Suunto 7 watch to record power using Sporty Go?

Sporty Go! is an app created by an independent developer which can be used with the Suunto 7 watch to record and display power from Stryd. Sporty Go! requires a premium purchase of the app's Bluetooth Package for use with Stryd. However, the app allows for a 60-minute free trial. Here's how to use it:

1. Download Sporty Go!:

2. Open the settings of Sporty Go! on the watch

3. Select the Bluetooth Package to open it

4. Select 'TRY'

5. Open the Bluetooth devices list

6. Move your Stryd to activate it (if Stryd does not appear in the list, make sure it is disconnected from any other device/app such as your phone)

7. Once Stryd has connected you can now start a workout

8. Select 'Power' and begin running

9. Your power should now appear on the watch.

Here's how to get your data into Stryd PowerCenter:

Within the Sporty Go! app you can choose to automatically export the FIT file to a Google Drive or a similar service. From there, you can import the FIT file into PowerCenter manually.
