The Forerunner 55 is designed for the runner in everyone. Whether you’re just getting started or are training for a race, the Forerunner 55 offers updated features that help you train smarter, not harder. Designers kept the lightweight, waterproof case and watch face but beefed up the battery life to double the time in Smartwatch mode (2 weeks to be exact) and up to 20 hours of GPS mode functionality. In addition to classic fitness tracking features like heart rate tracking and sleep monitoring, the Forerunner 55 also features new running metrics to enhance your race-day prep and daily training. Track mode provides increased accuracy on the track while features like PacePro Pacing Strategy, Predicted Race Times, Finish Time Estimator and Daily Suggested Workouts help you keep a pulse on your fitness and potential race performance, taking the guesswork out of race day strategy. In addition to updated running features, the Garmin Forerunner 55 now includes Women’s Health Tracking for menstruating or pregnant athletes.
