Still running on “empty” without all the real tools you need to enhance your run, expand your tracking to other activites, and easily move through your day? Set your eyes on the new Forerunner 645 and 645 Music. Strutting a suave metal bezel and interchangeable bands that takes the traditionally super sporty Forerunner line-up to office-appropriate, 645 delivers it all: advanced running dynamics, 24/7 heart rate and stress level monitoring, the ability to pay for purchases with your wallet safely back home, added sports like cycling, swimming, elliptical, cardio and more..and music storage if you choose. Because you’re not just a runner—you’re a well-rounded athlete with a life that moves quickly—and Forerunner 645/645 Music will go right along with you stride for stride.
Gotta have those background beats while you run, spin, or log in a cardio session? The 645 Music lets you download up to 500 songs right from your computer or from offline playlists you’ve saved via popular radio streaming services, including Deezer, iHeartRadio and more. Music version only.
Don’t sweat who might lift your wallet during a 5k or a run at the gym—leave your cash and credit cards safely at home and pay for race-day essentials, gas, coffee, water and more with the built-in contactless payment option.
In addition to the traditional pace and distance, get the numbers that will help improve your stride such as ground contact time balance, stride length, VO2 max, recovery time, race predictor, lactate threshold and vertical ratio.
Don’t just SEE your incoming text messages—respond to them too via prewritten messages that acknowledge texts quickly and easily.
Wandering a little outside of your comfort zone? 645 has GLONASS (in addition to GPS) to add even more satellites for accurate tracking wherever you decide to roam.
Are you training productively? 645 will let you know if you’ve overtrained or even started to peak, so you can make more informed decisions about your runs and fitness activity.
