The Garmin Forerunner 15 Watch captures essential stats from your run like time, distance and pace. Want to track the steps you take throughout your day when you?re not working out? Now you can, without wearing a separate activity tracking device. Forerunner 15 counts your steps and the calories you burn all day. When you upload your data to Garmin Connect, this allows you to monitor your progress toward fitness goals and see overall fitness trends. Forerunner 15 also reminds you when it?s time to move if you?ve been sitting for more than an hour. You won?t have to worry about charging Forerunner every night. The rechargeable battery will last up to 5 weeks in watch/activity tracking mode or 8 hours when using it with GPS on your outdoor runs. Forerunner 15 has a water rating of 5 ATM (50 meters), which means it resists rain and sweat and can even join you for a swim.
