    We made this watch for you — the up-at-dawn runners and the conditioned-for-pain triathletes. While you chase your next victory, make sure you’ve got the right tool for the job.

    ELITE RUNNING WATCH DESIGN
    When every bit of weight makes a difference, fight for the finish line with a lightweight smartwatch that doesn’t bulk up your wrist.

    MARATHON-READY MATERIALS
    Forerunner 945 is miles ahead of the competition with a high-performance silicone band and an ultra-durable Corning Gorilla Glass DX lens.

    GARMIN COACH
    These adaptive training plans feature guidance from expert coaches and free training plans that adapt to you and your goals. Workouts sync right to your watch.

    BUILT-IN SPORTS APPS
    Switch up your workout routine with activity profiles for cycling, pool and open-water swimming, track running, elliptical, stair-stepper and more.

    WRIST-BASED HEART RATE
    Get heart rate data4 along with alerts if your heart rate stays too high or too low while you’re at rest. Gauge how hard your heart is working during activities, even underwater.

    MULTI-GNSS
    Access multiple global navigation satellite systems (GPS, GLONASS and Galileo) to track in more challenging environments than GPS alone.

    RUNNING DYNAMICS
    When used with a compatible accessory, Forerunner 945 measures crucial running metrics such as cadence, stride length, ground contact time and balance and more.

    VO2 MAX
    Train smarter with VO2 max, an indicator of how you can expect to perform. This metric even accounts for changes in performance that could be caused by heat or altitude.

    PERFORMANCE CONDITION
    While you run, analyze pace, heart rate and heart rate variability for a real-time assessment of your current ability to perform.

    TRAINING STATUS
    This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.

    TRAINING EFFECT
    See how your workouts influence the development of endurance, speed and power with aerobic and anaerobic training effect feedback.

    TRAINING LOAD
    This stat measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.

    DAILY WORKOUT SUGGESTIONS
    For training guidance that takes you and your fitness level into account, get daily run and ride recommendations based on your current training load and training status.

    RECOVERY TIME
    After each workout, the built-in recovery time advisor lets you know how long to rest before another big effort. It even accounts for all-day stress, sleep and daily activity outside of workouts.
