The i-Run team says
Whether it's for your regular running sessions or your new sports challenges, the Garmin Forerunner 255S watch is a true tool for progression. Its advanced design allows you to reach your most demanding goals.
Equipped with the Elevate Gen 4 heart rate sensor and the Pulse Ox 2.0 pulse oximeter, it records valuable data about your fitness level. With this information, it offers you training recommendations and health insights right from the moment you wake up.
Multiple 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 excel in these disciplines.
To improve your performance, an analysis is conducted to optimize your recovery after exertion. The Garmin Connect app gives you access to organizing and creating workout sessions based on your level and goals.
Using constant calculation, the multi-band GPS pinpoints your location with great precision even in challenging areas. The barometric altimeter enhances your outdoor experience.
Ideal for self-care, it incorporates the Fitness Age 2.0 algorithm and the HRV test. The latter assesses the interval between two heartbeats to measure your fitness condition and stress level.
Available in two sizes, the color screen guarantees a pleasant use and a high shock resistance. Redesigned for better autonomy, it accompanies you for 26 hours in GPS mode and up to twelve days in connected mode.
