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 strap because this watch has a built-in sensor that measures heart rate at the wrist. A colorful gauge shows your zone and beats per minute at a glance: warm-up (gray), easy (blue), aerobic (green), threshold (orange) or maximum (red).
