Forerunner 220 measures essential running data including distance, pace and heart rate¹. It’s like having a coach on hand, providing constant feedback and recording all your stats so you can focus on your run. In addition to using GPS to calculate distance and pace, the 220 has a built-in accelerometer. So you know distance and pace data when you’re running on an indoor track or treadmill, with no need for a separate foot pod. The accelerometer can also track distance when GPS is unavailable, such as when you run through a tunnel. It’s compatible with free training plans from Garmin Connect, which you can schedule and send to your watch, for real-time coaching.
