I prefer running without my phone so I use a GPS watch instead - the Garmin Forerunner 10. This device is not equipped with bluetooth, so I upload my activity to Garmin Connect through Garmin Express then sync it across platforms with tapiriik. Set up as follows:
- Install Garmin Express, connect and add device: https://connect.garmin.com/en-US/start/forerunner/express
- In Garmin Express, select "view your activities on Garmin Connect" which will sync activity
- Hook up Garmin Connect to tapiriik which will provide the activity syncing across services
- Hook up any other services to sync to via tapiriik (I sync to Strava and Runkeeper)
- Activity will need to be synchronized manually via tapiriik (by selecting the "synchronize now" button) unless you pay for automatic synchronization (a trivial $2/year to cover costs, more for added support)
