Technical description

Technologies

• Fréquence cardiaque

  Permanently display your beats per minute to help you improve your physical condition.

• Running Dynamics

  1. Stride Length: Measure the distance traveled horizontally towards your destination.
  2. Ground Contact Time Balance: Measure your balance during ground contact to determine if your run is symmetrical.
  3. Vertical Ratio: Observe the effort required to move towards your destination. A low score indicates low energy expenditure or low bounce for a high stride length.

• Body Battery

  Optimize your body's energy reserves by using heart rate variability, stress, sleep, and other data to assess your fitness level or when you should rest.

• Pulse Ox

  Pulse measurement, a pulse oximeter measures the amount of oxygen (relative to the maximum capacity) in the blood as it moves through your body.

• LiveTrack

  Incident detection and assistance request functions.

• Garmin Coach

  Are you training for a 5K, 10K, or a half marathon? Download a custom-fit Garmin Coach training plan for free, tailored to your schedule and abilities.

• Garmin Connect

  Garmin Connect is an online community where athletes can connect and compete by participating in challenges, encouraging each other, and sharing their performances via social networks. Garmin Connect is free and available on your smartphone with the Garmin Connect Mobile app.

• VO2 Max

  Train smarter with VO2 Max, an indicator of your performance.

• Garmin Connect IQ

  Personalize your watch with watch faces, data fields, apps, and free widgets from the Connect IQ TM store.

• PacePro

  Plan your race strategy with the PacePro TM 3 feature that offers GPS pace guidance based on elevation for a selected course or distance in the Garmin Connect TM app.

• Profil d'activité HIIT

  Proposal for a selection of HIIT training options, such as AMRAP, EMOM, Tabata, and much more. HIIT provides tips throughout your workouts, sets the number of rounds, and chooses the work/rest intervals.

• Race Predictor Trend

  The Race Predictor function displays, on a graph, the evolution of race time predictions over the long term, allowing you to better track the development of your capabilities and performance.

• GNSS Multi-bandes

  This unique new feature from Garmin is a technological achievement, delivering unparalleled GPS location accuracy. Thanks to the constant recalibration of position by the watch on both frequencies of each multi-band compatible GNSS network, this technology effectively identifies and eliminates erroneous positioning data, thereby offering much higher accuracy, especially in canyons, cities, and challenging alpine environments.

• Elevate

  The wrist-based optical heart rate monitor of Garmin smartwatches is a useful tool that enables the user to obtain precise heart rate estimates at any time. The optical heart rate monitor is designed to monitor the user's heart rate 24 hours a day, 7 days a week.

• Suivi menstruel et grossesse 2.0

  Allows you to track menstrual cycles and display cycle details as well as other statistics on Garmin Connect.

• Fitness Age 2.0

  New algorithm using the user's chronological age, VO2 Max, resting heart rate, and either BMI or body fat percentage (BMI will be used if body fat percentage is not available). Indicates to users whether their body is "older" or "younger" than they are.

• Suivi de respiration 2.0

  Enables the consultation of respiration data throughout the day, during sleep, and during yoga and breathing activities.

• Test HRV/VFC

  Heart rate variability is the variation in the time interval between two heartbeats. The level of HRV varies greatly among individuals, but in general, a high HRV is considered a marker of good physical fitness and health, while a low HRV is associated with negative health effects and a high level of stress.

• Profil d'activité Piste

  For greater accuracy on the track, the track activity profile increases the frequency of GPS position updates.

• Running Power

  The "Running Power" feature utilizes metrics such as pace, vertical oscillation, slope, and even wind force to calculate the power in watts that you apply to the ground while running. By knowing the power you expend each minute and each kilometer, you can manage your pace more effectively and thus better manage your effort.

• Entraînements animés

  More than 1400 fully customizable exercises available. Displays the muscle groups worked during the activity directly on the watch.

• Live Events

  Live Events Sharing (Android only) allows your entourage to interact via text messages and send encouragements.

• Puissance en course à pied

  The running power function developed by Garmin utilizes metrics such as pace, vertical oscillation, incline, and even wind resistance to calculate the power you transfer to the ground while running.

  By obtaining the power you expend each minute and each kilometer, you can manage your pace more easily and thus avoid tiring yourself out too quickly.

• Rythme adapté à la pente

  Whether uphill or downhill, runners can now obtain their equivalent pace on flat terrain, making it easier to maintain a steady effort.
