The i-Run team says
Whether it's for your regular running sessions or your new athletic challenges, the Garmin Forerunner 255 watch is a true tool for progression. 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 about your fitness level. Thanks to this information, it offers training recommendations and health insights right from the moment you wake up.
Several sport 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 perform best in these disciplines.
To improve your performance, an analysis is conducted to optimize your recovery after effort. The Garmin Connect app gives you access to organizing and creating workout sessions tailored to your level and goals.
With constant calculation, the multi-band GPS locates your position with high precision even in challenging locations. The barometric altimeter enhances your experience during your outdoor adventures.
Ideal for self-care, it incorporates the Fitness Age 2.0 algorithm and the HRV test. The latter evaluates the interval of time between two heartbeats to measure your physical condition and stress level.
Available in two sizes, the color screen ensures a pleasant user experience and great shock resistance. Redesigned for better autonomy, it supports you for 30 hours in GPS mode and up to fourteen days in connected mode.
