OVERVIEW:
[NON-MUSIC]
Running is more than just exercise — it’s a performance. And Forerunner 645 has the tools to help you put on an outstanding show every time you lace up your shoes. Featuring contactless payments that let you buy what you need while on the go — plus advanced running dynamics and performance monitoring tools — this GPS running watch is the instrument you need to refine the performance.
Tune up Your Training: We’re making it easier to get the data you need to improve your form. Let Forerunner 645 measure crucial running metrics that you can use to analyze your performance. Biomechanical measurements², such as cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio, are the key to understanding your form so you can bring your best on race day. These metrics are available with the addition of a compatible heart rate strap or the compact Running Dynamics Pod, which clips right onto your waistband. Also, take advantage of feature sets to help with cycling and even swim training. In the pool, Forerunner 645 will track your distance, pace, stroke count and more.
Monitor Your Performance: Just how effective is your current training plan? Forerunner 645 will help you monitor your training and recovery so you can better prepare for a race or training cycle. Training status is a performance monitoring tool that automatically evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching. The anaerobic training effect metric opens a window of insight to a critical dimension of training, telling you how your training is improving your ability to push the limits. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
More Ways to Customize: Check out our Connect IQ store, where you can add personality to Forerunner 645 by downloading apps, widgets, watch faces and more. It’s easy and — even better — it’s free. New apps are added every day, so you can keep tabs on when your Uber is arriving, turn on your lights at home with the SmartThings app, and even use the AccuWeather MinuteCast app to find out when the rain will start. With the Face It™ watch face app, choose any image from your photo library, make some tweaks, and set it as your watch’s face.
Stay Connected on the Run: Forerunner 645 makes it easy to run without leaving important smart features behind. Once paired with your compatible smartphone, you’ll be able to receive and even respond6 to text messages and see social media updates, emails and more right on your wrist. Find your phone, access music controls, and let friends LiveTrack your runs.
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 with the Garmin Connect™ Mobileapp.
Train Your Way: Your routine is anything but routine. Forerunner 645 lets you change things up with ease, thanks to built-in activity profiles for running (indoor/outdoor), cycling (indoor/outdoor), swimming (pool), elliptical, paddle sports, strength training and many more. Create your own custom workouts, and download for free from our Garmin Connect online fitness community. Then review your past efforts on the app, or share them with family and friends for added motivation.
Love the Look: Designed for runners, Forerunner 645 features a reliable five-button interface that lets you mark laps with a quick press. Feel free to take this watch outside in all kinds of weather. Not only is it safe for swimming and showering, its Garmin Chroma Display™ is easy to read — even in direct sunlight — and housed under chemically strengthened glass. When you want to change it up, swapping bands is fast and doesn’t require tools. And with up to 7 days of battery life in smartwatch mode and 12 hours in GPS mode, Forerunner 645 is the running partner that can keep up with you.
[MUSIC]
Music: With up to 500 songs worth of music storage built right into your watch, we’re putting the “beat” in your daily mission to beat yesterday. It’s easy to transfer music from your computer and then queue up your favorite playlist for easy listening through Bluetooth headphones. You can even sync your carefully crafted playlists from select music streaming services¹ to your watch for more ad-free listening. Now you really can leave your phone behind when you head out for a run, because the music that helps keep you moving is right there on your wrist.
