Long runs, tempo runs, speed drills. You expect a lot from your body and from your training gear. Garmin’s line of GPS-enabled sport watches can track your training, then wirelessly send your data to your computer. Loaded with serious training features, Garmin watches can continuously monitor your time, distance, pace, calories and heart rate (when paired with heart rate monitor). Each run is stored in memory so you can review and analyze the data to see how you’ve improved. With some models, you even can download recorded courses to compete against previous workouts or race a Virtual Partner.
