The i-Run team says
Whether it's for your regular running sessions or your new sports challenges, the Garmin Forerunner 255S Music watch is a true tool for progress. Its advanced design allows you to achieve your most demanding goals.
Equipped with the Elevate Gen 4 heart rate sensor and Pulse Ox 2.0 pulse oximeter, it records valuable data on your fitness level. With this information, it offers you training recommendations and health reports from the moment you wake up.
Several sports profiles are available to help you make the most of your activities. A swimming mode for both pool and open water provides the necessary elements to optimize your performance in these disciplines.
To improve your performance, an analysis is conducted to optimize your recovery after exertion. The Garmin Connect application gives you access to the organization and creation of training sessions by considering your level and goals.
With constant calculations, the multi-band GPS locates your position with great precision even in challenging areas. The barometric altimeter enhances your experience during outdoor outings.
Ideal for self-care, it incorporates the Fitness Age 2.0 algorithm and the HRV test. The latter measures the interval between two heartbeats to assess your physical condition and stress levels.
Keep your motivation at its peak by listening to your favorite tracks directly stored on your watch. Link your Spotify or Deezer account and control your playlists during your activities.
Available in two sizes, the color screen ensures pleasant use and high shock resistance. Redesigned for better autonomy, it follows you for 26 hours in GPS mode and up to twelve days in connected mode.
