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 night¹.

Run Your Heart Out

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. As part of your training plan, it can even help you predict your race time. And the workouts sync right to your watch.

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 detection³. 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. And when paired with your compatible smartphone, Forerunner 45 will automatically upload your run data to the Garmin Connect online fitness community. It even has handy controls for the music playing on your phone, so you can skip songs without missing a beat.

Stay Connected and Secure

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 sleep¹. 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. And to help you optimize your body’s energy, Body Battery energy monitoring uses collected data to gauge your energy reserves at any moment, so you can plan your day to optimize times for activity and rest.

Share and Compete

Syncing your activities to Garmin Connect is for more than just storing your data. Garmin Connect is a thriving online community where people on the go can connect and compete by joining challenges, encourage each other’s successes and even share their triumphs via social media. Garmin Connect is free and available on the web or on your smartphone.
