    GroupTrack for When You Pull Away from the Pack

    Even when you pull away from the peloton, there’s no need to feel alone. Our new feature, GroupTrack¹, allows you to pair your device through Garmin Connect™ so you can keep tabs on your riding buddies, and they can keep tabs on you when you get separated. It’s just 1 of the innovations we’re rolling out to make your ride feel more connected.


    The Touchscreen You’ve Been Waiting For

    You’re going to enjoy using all the powerful features packed inside Edge 820’s compact body, but you’re going to really love the high-resolution touchscreen. An ambient light sensor automatically adjusts the screen’s brightness, so it’s easy for you to see at a glance, and the capacitive touch display is responsive — even when wet or used with gloves.


    Advanced Performance Monitoring

    Edge 820 GPS bike computer is compatible with ANT+® sensors, including speed, cadence and heart rate. For even more performance data, the 820 is also compatible with ANT+ power meters, including Vector™, our unique pedal-based power meter that measures total power, left/right balance and cadence. It integrates with ANT+ electronic shifting systems and ANT+ bike trainers. You can even record cycling dynamics to get a better look at your form, including where your power is being applied on the pedal and throughout the pedal stroke.

    With the addition of a heart rate strap, you gain access to a variety of physiological data. See your cycling-specific VO2 max along with a recovery advisor, which analyzes your data and tells you how long you should wait before attempting another hard ride. This connected system of sensors, accessories, cycling computer and post-ride analysis at Garmin Connect allows you to keep track of how your body performs from ride to ride.


    Varia Compatibility for Increased Cycling Awareness

    Edge 820 offers incident detection capabilities via an integrated accelerometer and sends your location to an emergency contact if you get into difficulty. To assist with incident avoidance, Edge 820 is also compatible with our wide range of Varia™ cycling awareness products, including rearview radar and smart bike lights for unparalleled awareness of your environment as you ride. See and be seen when Edge 820 is paired with these bike lights or the radar, which detects approaching traffic.
