Strap Garmin's Forerunner 220 to your wrist and bring your own personal coach along for every run. On a basic level, the 220 delivers easy-to-read data (including distance, pace, and time) so that you can focus on your running. But this is no simple timepiece. It's large, high-resolution color display features customizable screens that allow you to keep it simple or choose from a wealth of helpful training data. With Garmin Connect, you can upload your workouts for logging and analysis, download workout files to your GPS, and even share your latest adventure through your favorite social media website. Paired with your smartphone (iPhone 4S or later, sold separately) via Bluetooth, this on-hand coach enables live GPS tracking so your friends, family or coach can follow your progress during workouts or races. In addition to GPS technology, a built-in accelerometer lets you track pace and distance data while running on a treadmill, through a tunnel, or on an indoor track—all without a separate foot pod. The 220 will inform you when you've set a new personal record, and it even offers vibration or audio alerts to keep you on pace.
