ENDURANCE SCOREThis feature measures your ability to sustain prolonged efforts and combines training data from all your athletic pursuits to help you understand how training impacts your overall endurance. |
HILL SCOREThis feature measures your capability for running uphill and evaluates your progress over time based on your VO2 max and training history. |
TRAINING READINESSFrom the moment you wake up, get a readiness score based on your sleep quality, recovery, training load and more, so you can determine whether it’s a good day to go hard — or take it easy. |
TRAINING STATUSUsing indicators such as HRV status, your recent exercise history and performance, get an easy insight into your overall effort — and whether you’re training productively, peaking or strained. |
WRIST-BASED RUNNING POWERSee how much power you’re applying to the trail or the road so you can manage your effort and fine-tune your training. No accessory required. |
HRV STATUSGain a deeper understanding of your overall health, training and recovery through heart rate variability while you sleep, based on technology developed by our Firstbeat Analytics™ team. |
RACE WIDGETGet ready for your next race with training tips, personalized daily suggested workouts and completion time predictions based on course details, weather and performance. |
ANIMATED WORKOUTSThis tool watch features easy-to-follow, animated cardio, strength, yoga and Pilates workouts you can view on the watch screen. Choose from preloaded animated workouts, or download more from the Garmin Connect™ online community when paired with your compatible device. |

VISUAL RACE PREDICTORBased on your running history and overall fitness level, get an estimate of what your pace could be for a 5K, 10K — or even a marathon. Plus, trend data highlights your training's impact over time. |
PACEPRO™ TECHNOLOGYA first-of-its-kind PacePro feature helps keep you on pace with grade-adjusted guidance as you run a course. |
VO2 MAXTrain smarter with VO2 max, an indicator of how you can expect to perform. It adjusts for trail running and accounts for changes in performance that could be caused by heat or altitude. |
REAL-TIME STAMINAUse this real-time stamina data to track and manage your exertion — and help avoid overexerting at the start of your run or bike activity. |
GRADE-ADJUSTED PACEDon't run out of steam before the activity is over. Understand how to adjust your pace over varying terrain to perform according to your plan. |
RECOVERY TIMEAfter each workout, recovery time lets you know when you'll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep. |
JET LAG ADVISERHelp minimize the effects of jet lag with guidance on light exposure, sleep schedule and exercise on your next long-distance trip. Enter your travel details in the Garmin Connect app calendar, and track how your body clock is adjusting to your new destination. |
MORNING REPORTReceive an overview of your sleep, recovery and training outlook as soon as you wake up — alongside HRV status, training readiness and weather. Customise your report to see the data you want. |
WRIST-BASED HEART RATEThis tool watch constantly samples your heart rate1 and will alert you if it stays too high or too low while you're at rest. It also helps gauge how hard you work during activities — even while swimming. |
SLEEP SCORE AND ADVANCED SLEEP MONITORINGGet a full breakdown of your light, deep and REM sleep stages. View it all on a dedicated widget that includes your sleep score and insights. |
BODY BATTERY™ ENERGY MONITORINGOptimise your body's energy reserves by using heart rate variability, stress, sleep and other data to gauge when you're ready to be active or when you may need to rest. |
STRESS TRACKINGHeart rate variability is used to calculate your stress level score, so you can see if you're having a calm, balanced or stressful day. |
