The popularity of Garmin's Vivofit has been overwhelming. But when you train, you don't want to wear two watches. For this reason, Garmin has combined the daily activity tracker of the Vivofit with the metrics of the Forerunner in the Forerunner 15. The Forerunner is predominantly designed for tuning up your running. It needs no programming and is ready to go the moment you put it on. For more focused training, you're able to program settings to show pace and distance and provide audible feedback for each interval or mile you complete. There's even a walk/run feature for beginning runners. Once your run is finished, you're able to upload the data through Garmin Connect to peruse it obsessively. In addition to running support, the Forerunner 15 comes with an ANT+ Sensor that will sync with Garmin's Foot Pod and Heart Rate monitor.
