Know your zone with Forerunner 225 — the first Garmin GPS running watch with wrist-based heart rate. Now you have the option to run without a heart rate strap because this watch has a built-in sensor using Mio Heart Rate Technology that measures heart rate at the wrist. We didn’t just get rid of the heart strap on the 225, we also refined how this watch sums up your effort. A colorful gauge identifies your heart rate zone and beats per minute in real time.
