Some fitness watches are great for running. Others for cycling, and still others for swimming. But if you're a triathlete, what do you do? Wear three devices? No, you just wear the Garmin Forerunner 920XT Multisport Watch. Designed to excel in all three activities, it offers stroke and distance tracking in the water, distance, route, and gradient data while cycling, and a metronome with vibration for on-foot cadence training. It becomes even more powerful when used with compatible sensors measuring heart rate, speed, and power, links to your phone for automatic uploading of your data to Garmin Connect, and, like any good wearable, offers smart notifications, too.
