See yourself as a runner. Forerunner® 55 is the GPS running smartwatch that goes beyond pace and heart rate (this is not a medical device) stats. Take the guesswork out of training with personalized guidance and daily suggested workouts based on your training history and fitness level. Change things up with HIIT and breathwork activity profiles. Advanced wellness tracking features, such as all-day respiration monitoring, intensity minutes, and more, put you in tune with your body. Get more runs in between charges, thanks to this watch’s longer battery life, and make it truly your own by downloading watch faces, apps, and more from the Connect IQ™ Store (requires Garmin Connect™ app and Connect IQ™ app loaded on a compatible smartphone).
