TRAINING STATUS Using new 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. ACUTE LOAD See your training history, and compare the intensity of your recent workouts to the optimal range to help improve your fitness. TRAINING EFFECT See how your workouts influence your endurance, speed and power with aerobic and anaerobic training effect feedback. PERFORMANCE CONDITION While you run, get an analysis of your pace and heart rate for a real-time assessment of your current ability to perform. RUNNING DYNAMICS When using a Running Dynamics Pod or HRM-Pro monitor, the Forerunner 255 watch measures crucial running metrics such as cadence, stride length, ground contact time and balance, and more — while comparing to others in the Garmin Connect app. COURSES Create or find existing courses in the Garmin Connect app, so you’ll never run out of places to run. Or plan one on other platforms such as Strava and Komoot, then automatically sync them to your Forerunner. VISUAL RACE PREDICTOR Based 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. CROSS-TRAINING Mix up your training with different types of workouts. Free HIIT, strength, cardio, yoga and Pilates workouts come preloaded on the watch, and you can download more from the Garmin Connect app. WRIST-BASED HEART RATE The watch constantly samples your heart rate with our latest-generation heart rate sensor 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. BODY BATTERY ENERGY MONITORING Track your body’s energy levels so you can find the best times for activity and rest. IMPROVED SLEEP MONITORING AND SLEEP SCORE Understand how your body is recovering — and get ready for training — with our improved sleep monitoring feature. After waking up, you’ll receive a sleep score, as well as breakdown of your sleep stages, Pulse Ox and respiration, alongside detailed insights for improved sleep quality. PULSE OX SENSOR This wrist-based Pulse Ox sensor monitors blood oxygen saturation levels to support advanced sleep monitoring and altitude acclimation. WOMEN’S HEALTH TRACKING Use the Garmin Connect app to track your menstrual cycle or pregnancy. Log symptoms, get exercise and nutrition education, and more. Even see and log details on your wrist with the Women’s Health Tracking app. INTENSITY MINUTES Our intensity minutes feature tells you when during the day you earned them and during what activity. STRESS TRACKING Find out if you’re having a calm, balanced or stressful day. Relax reminders will even prompt you to do a short breathing activity when the watch detects that you’re feeling stressed. HEALTH SNAPSHOT FEATURE Log a 2-minute session to record key stats, including heart rate, heart rate variability, Pulse Ox, respiration and stress. Then generate a report with those stats to share via the Garmin Connect app on your compatible smartphone. MULTI-BAND GNSS SUPPORT Access multiple global navigation satellite systems, and get access to multiple frequencies sent by navigation satellites for improved accuracy in areas where GNSS signals are reflected, weak or typically don't penetrate — giving you superior accuracy for how far and how fast you’ve run — even in challenging environments. GARMIN PAY CONTACTLESS PAYMENTS Breeze through checkout lines with Garmin Pay contactless payments through participating providers. SMART NOTIFICATIONS Receive emails, texts and alerts right on your watch when paired with your Apple® or Android smartphone. You can even respond to texts if you have an Android phone.
