Get fit with the Garmin Forerunner running watch. This running watch has a built-in GPS that tracks your run, including distance and speed, without requiring you to carry a phone. A wrist-based heart monitor in the Garmin Forerunner running watch records your heartbeat all day so you can easily monitor your fitness level.
I owned a Fitbit Blaze for four months before Garmin came out with the Forerunner. I enjoy the Garmin so much more because of its GPS (you don't have to wait for it to sync with the app like the Fitbit), the tracker, and the screen.
The designs are similar but the Blaze is bulkier so I prefer the FR.
