Garmin announced the new Edge 820 and Edge Explore 820 this week. Triathletes and anyone who refers to a bike ride as "training" should take a look at the Edge 820. The Edge Explore 820 lacks power meter support, structured workouts, and cycling analysis features, but is great for touring riders.
We've been looking forward to an update to the Edge 800-series for some time and here it is. The Edge 820 has the soul of the 800-series (navigation in addition to training) in the size of the 500-series with some of the features that have been popping up in other Garmin products plus some brand new features. The Edge 820's little sibling, the Edge Explore 820, dials back the advanced training features, but still has ANT+ connectivity for heart rate, speed, and cadence sensors that you would not find in a typical navigation device.
