The Garmin Forerunner 255 sports watch is your companion for both regular running sessions and new athletic challenges. Its sophisticated design is crafted to help you achieve even the most demanding goals.
You have access to over 30 sports profiles, enabling you to get the best out of yourself in activities including running, cycling, triathlon, hiking, and swimming. In swimming, you can choose between pool swimming and open water modes.
The Garmin Forerunner 255 is equipped with the Elevate Gen 4 heart rate sensor and the Pulse Ox 2.0 oximeter, capturing crucial fitness data. Based on these insights, it offers training recommendations and health data right after you wake up.
An analysis is performed to enhance your performance, helping you optimize recovery after exertion. The Garmin Connect App allows you to organize and create workouts tailored to your level and goals.
The multi-band GPS precisely calculates your position even in challenging environments, and the barometric altimeter is beneficial for your outdoor excursions.
The watch features the Fitness Age 2.0 algorithm and the HRV test, enabling you to monitor your health status. The HRV test measures the time interval between heartbeats to assess your fitness and stress levels.
Redesigned for longer battery life, the watch runs up to 30 hours in GPS mode and up to 14 days in smartwatch mode.
More than 30 Sports Profiles
Multiband GPS and Multi-GNSS (GPS, GLONASS, GALILEO): for accurate positioning, even in canyons and in the city.
Elevate Gen 4 Heart Rate Sensor: 24/7 heart rate monitoring, even underwater
Pulse Ox 2.0 Oximeter: Blood oxygen saturation
Barometric Altimeter: Analyzes elevation differences and storm risks
Compass, Accelerometer, and Thermometer
24/7 Activity Tracker: Step counter, sleep, calories, floors, distance, physical age, daily effort, and intensity minutes
Automatic Training Recommendations based on your fitness, stress level, and sleep.
The silicone strap and charging cable are included in the package of the watch.
Permanently display your beats per minute to help you improve your physical condition.
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 measurement, a pulse oximeter measures the amount of oxygen (relative to the maximum capacity) in the blood as it moves through your body.
Incident detection and assistance request functions.

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.
Train smarter with VO2 Max, an indicator of your performance.
Personalize your watch with watch faces, data fields, apps, and free widgets from the Connect IQ TM store.
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.
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.
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.
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.
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.
Allows you to track menstrual cycles and display cycle details as well as other statistics on Garmin Connect.
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.
Enables the consultation of respiration data throughout the day, during sleep, and during yoga and breathing activities.
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.
For greater accuracy on the track, the track activity profile increases the frequency of GPS position updates.
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.
More than 1400 fully customizable exercises available. Displays the muscle groups worked during the activity directly on the watch.
Live Events Sharing (Android only) allows your entourage to interact via text messages and send encouragements.
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.
Whether uphill or downhill, runners can now obtain their equivalent pace on flat terrain, making it easier to maintain a steady effort.
