I always run on treadmill. I got this email back from Stryd.
On FR965, we recommend to use the Stryd Zones data field. Please find setup instructions for that here: https://help.stryd.com/en/articles/8538812-getting-started-stryd-zones-update-workout-import-for-garmin-watches#h_48b3acb7a3
Is this the best way? is there another way to use both together on treadmill? Thanks.
