Product details
Running is not only about training, but also about performance. The Forerunner 645 offers just the right tools to keep you perfectly equipped every time you put on your running shoes.
Want to buy something? With contactless payment, you won't miss a step. You also get advanced running efficiency values and performance tools. This GPS performance running watch is simply a great all-rounder.
The watch has space for up to 500 songs to keep the right music with you on every lap. Easily transfer music from your computer to your watch, select your favourite playlist and connect your Bluetooth headphones. Now you can really leave your phone at home while you run, because the music that motivates you is stored directly on the Wearable. If you have a Deezer Premium+ subscriber, you can even sync your carefully crafted playlist with your watch to listen to even more music without ads (coming soon).
Always on the go? Just leave your phone and wallet at home. Forerunner 645 supports contactless payment with Garmin Pay ready, so you only need your watch when shopping. It can be used wherever contactless payment is supported. Whether it's a bottle of water or a snack, you can pay in no time at all and get back on the road.
Certain data will help you improve your shape. We provide you with this data. The Forerunner 645 Music measures important running efficiency values that you can use to analyze your performance. Biomechanical values such as stride frequency, stride length, ground contact time and ground contact time balance, vertical movement and vertical ratio are essential if you want to know your shape to give your best on race day. You'll get these values when you use a compatible heart rate chest strap or the compact Running Dynamics Pod that attaches to the waistband of your clothes. Also use special functions for cycling and even for swim training. In the water, Forerunner 645 Music measures distance, pace, number of moves and more.
Keep an eye on your performance: How effective is your current training plan really? Forerunner 645 Music helps you monitor your training and recovery so you can better prepare for competition or a training phase. Training Condition is a new performance tool that automatically evaluates your most recent workouts and performance indicators and tells you whether you're building form, reaching peak form, or overworked. The new anaerobic Training Effect provides an insight into an important part of your training and tells you whether your training improves your ability to train very intensively. You can even see your general training load. It compares your training volume over the last 7 days with the optimal range for your fitness level and your last workouts.
