Run Your Heart Out

This easy-to-use running watch is perfect for daily runs, training sessions and even that upcoming 10K you got talked into. Built-in GPS tracks where you run and gives you accurate stats, including distance, pace and intervals. And its intuitive button interface makes it easy for sweaty hands to mark a lap or pause the timer. Forerunner 45 also monitors heart rate at the wrist, day and night.

Gear up with Garmin Coach

Whether you’re a seasoned runner or just getting off the couch, everyone can use a little bit of guidance. That’s why Forerunner 45 is compatible with Garmin Coach adaptive training plans. These plans feature guidance from expert coaches and free training plans that adapt to you and your goals. It’s a foolproof way to get to the finish line. 

Stay Connected on the Run

Safety and tracking features make it easy to share your location with chosen contacts in case you need assistance — manually, or automatically with built-in incident detection. And a variety of connected features keeps you in touch with the rest of the world during and in between runs. Get smart notifications delivered to your wrist for incoming text messages and phone calls.

There’s More to Do

With a dozen activity profiles available, you’ll always have a way to capture your sweat equity, even when you don’t feel like running. Forerunner 45 can record your efforts during a cycling workout, on the treadmill, indoor track and elliptical — and while doing cardio, yoga and more.

On the Way to Wellness

The Forerunner 45 GPS running watch offers extensive activity and wellness tracking features. Wear it 24/7 to monitor daily steps, distance, calories burned and even sleep. This smartwatch also features all-day stress monitoring for wellness tracking during the day. If your stress level starts to climb, use the relaxation breathing timer for a few minutes of guided breathing, which can help calm your mind and body.
