If your music belongs to running just as a detailed analysis of your running efficiency and your training progress do, the Forerunner 645 Music GPS running watch will be the ideal partner on your wrist. Up to 500 songs can be saved directly on the 42,2 g light watch with its total memory of 4 GB. They can be listened to conveniently during training with your connected Bluetooth earphones. As a Deezer Premium+ subscriber, you can even synchronise your carefully selected playlist with the watch and listen to it offline (if available). With this, you can really leave your smartphone at home for running. Yet the 645 Music is a lot more than just storage space for your favourite playlist. Elaborate analysis features, e.g. running efficiency values, VO2max estimate, training status and training load as well as aerobic and anaerobic training effects and the possibility to create your own training plans turn the GPS performance heart rate watch into your personal high-performance trainer.

In everyday life, the discreet and trendy Garmin Forerunner 645 works as a practical 24/7 fitness tracker, which converts your daily activities into a number of steps and calories burned and monitors the quality of your sleep. With Smart Notifications, you will be informed about calls, text messages, e-mails or social media updates directly on your wearable to stay-up-date in social life as well. Users of Android smartphones can even reply directly from their watch. The optical heart rate sensor for wrist-based heart rate measurement is integrated in the back of the housing and gives you important vital data in everyday life as well as during training.

Yet this watch is not only perfect for runners. Garmin has also given the Forerunner 645 extensive cycling and swimming features as well as diverse outdoor features, e.g. for skiing, snowboarding, cross-country skiing, stand-up paddling or rowing and thus turned this watch into a true allrounder. It even feels at home in fitness studios and supports you with several, already preloaded activity profiles during strength training or sweat-inducing cardio workouts. Should you lose orientation during your outdoor activities once in a while nevertheless, you can get back into civilization with TrackBack navigation. It is also possible to navigate on tracks that have been downloaded beforehand or to follow a waypoint navigation.

You can not only save and analyse your training data on the free online community Garmin Connect, yet also get in touch with other members and compete with them in online challenges. This is stimulating and motivating. You can easily share your success with others in other social media. Garmin Connect is available online and on your smartphone with the Garmin Connect mobile app. In Garmin’s Connect IQ Shop, which is also free, you can individualise your Forerunner 645 with downloadable apps, widgets, display designs and a lot more.
