With up to 11 days in smartwatch mode and up to 19 hours in GPS mode, you’ll get a more complete picture of your health and training.

Track your body’s energy levels to find the best times for activity and rest1. Even get details and insights on how sleep, naps, activities and stress impact your energy. Create or find existing courses in the Garmin Connect app and from favourite third-party platforms, and sync directly to your watch. Get an estimate of what your pace could be for a 5K, 10K, half-marathon and even a marathon. Automatically track or log your naps to see how they benefit your body and what their ideal time and duration should be. Track and log your menstrual cycle or pregnancy and get exercise and nutrition education.
Constant measurement of your heart rate helps you gauge how hard you work during activities, so you can stay in the know all day and night. Get measurements of crucial running metrics such as cadence, stride length, ground contact time and more to help improve your running form. See your current fitness level, and track changes over time to set goals, evaluate progress and more. Track your moderate and vigorous activity minutes to help meet your goals. Gain a deeper understanding of your overall health, training and recovery through heart rate variability. Get audio updates about your performance when paired to your smartphone. Find out if you’re having a calm, balanced or stressful day. Track your blood oxygen saturation while you’re awake or asleep.

Keep tabs on your daily steps, calories burned, floors climbed and more from your wrist. Estimate how fit you are compared to your actual age.
