Garmin Edge 820 is the compact, touchscreen cycling computer for competitors and serious achievers. Get the accuracy of turn-by-turn GPS navigation and an altimeter to tell you how fast, how high, how far you’ve gone and where you’ve travelled. Whether you’re training for a race or just trying to reach your personal goals, Edge 820 gives you high-tech performance monitoring like VO2 max, recovery advisor time and enhanced cycling dynamics when used with a Garmin heart rate monitor and power meter (both sold separately). Comprehensive cycling awareness features include built-in incident detection for road cycling use and compatibility with Garmin Varia rear view radar. The GroupTrack feature allows you to keep tabs on other riders in your pack, in-ride challenges through strava live segments, notifications when used with a compatible mobile phone and customisation options from Connect IQ.
