With personalized adaptive training programs and a vibrant display, it guides you towards your goals and illuminates your journey. This easy-to-use GPS running smartwatch provides the essential features you need to take your running to the next level — including GPS, pace, distance and wrist-based heart rate. Get workouts made for you. They adapt after every run to match your performance and recovery as well as the races coming up in your Garmin Connect smartphone app calendar. Get free adaptive 5K, 10K and half-marathon training plans from expert coaches to help you take on a new challenge. Get ready for your race with training tips, personalised daily suggested workouts and completion time predictions based on race details you enter into Garmin Connect.

With training effect, you can see how your workouts impact your fitness and understand the primary benefit from training runs and workouts.

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. Know how long to recover before your next high-effort workout based on your latest training as well as overall stress, sleep and daily activities outside of workouts. Understand how your body is recovering with sleep score, get a breakdown of your sleep stages, and gain detailed insights for improved sleep quality. 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. Browse the Garmin Connect app for dozens of free HIIT, strength, cardio, yoga and Pilates workouts. You can even build your own in the app and send them to your watch. Log a 2-minute session to record key health stats, then generate a report to share with your healthcare provider. 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. 

Garmin's built-in sensors connect to multiple satellite systems so you track where you run, and get accurate stats, including distance and pace. See how much power you’re applying to the trail or road so you can manage effort and fine-tune training. Tap in to 25+ built-in activities, including cycling, open-water swimming, strength training and more. Record accurate lap distances, and see your distances in metres.
