Run with all your heart. Forerunner 15 captures essential stats from your run like time, distance and pace. When paired with a heart rate strap¹, it also records your heart rate and heart rate zone so you'll know when you hit your target. Training with heart rate also allows you to monitor when you need to rein it in and when you can push yourself harder.

Monitor Your Activity Between Runs

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 , 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. When you get that cue to move, just walk for a couple of minutes to reset the inactivity indicator.

Motivation by the Mile

Forerunner 15 has an auto lap function that automatically alerts you when you complete each mile, giving you a friendly beep and a backlit screen that flashes your time for that mile. When you complete your run and save it, you’ll see a summary of how you did, including your total time, distance, average pace and calories. Forerunner 15 even lets you know when you achieve a personal record, like your fastest mile or longest run to date.

Train Indoors or Out

For outdoor runs, Forerunner 15 uses GPS to accurately record your time, pace and distance. To track distance and pace when you hit the treadmill or an indoor track, just pair Forerunner 15 with an optional , which attaches to the laces of your shoe.
