When does elevation data not come from Stryd?
When you run with a GPS watch the elevation data will likely come from the watch instead of Stryd, no matter how the watch is configured. This applies to Garmin, Suunto, and Polar (in most configurations). Some GPS watches are not very good at measuring elevation, this will show in the data.
When does Stryd provide elevation data?
If you are running with the Stryd app on your phone or Apple Watch, elevation will come from Stryd. This is also the case for running without a watch and just Stryd (and uploading the Stryd data with your phone after your run).
If I use a watch, can I still get the elevation data as recorded by Stryd?
Stryd will store 40 hours of running history on the device which includes elevation as recorded by Stryd. You can upload the Stryd data with the Stryd app on your phone. If you use a Garmin watch, set up a secondary Stryd account with a different email address to avoid duplication of data in your primary account.
Elevation data in PowerCenter and the Stryd app on the phone
PowerCenter will display your elevation as stored in the FIT file. In most cases, the elevation data displayed in PowerCenter will come from the GPS on your watch but there are some exceptions.
