By monitoring key aspects of your cycling and fitness progress, you get a better look at your current performance level and what you need to do to keep up the good work or continue improving. Selected Garmin devices collect data while you ride in order to bring you these cycling metrics and physiological measurements. It’s worth noting that some of these metrics need additional sensors such as power and heart rate. If your device is showing you stats, but you want to know more about what they mean, then you’ve come to the right place. What can you do with this calculated information? That’s up to you, but we’ve got some suggestions.
