Why We Like The Forerunner 255S

Positioned as a mid-tier smartwatch option from Garmin, the Forerunner 255S lets us dial in our running and training efforts with a low-profile device. Designed with the same feature set as the Forerunner 255, the 255S has a slightly smaller display and lighter design that stays out of the way during dynamic exercise. This watch provides all of the features we need to push further, with built-in race training features, pace management tools, and even settings to help regulate our caloric intake. It’s packed with adventure-ready features for a wide range of disciplines, with a multi-band GPS, submersible design, and cycling-focused features for mountain biking and road cycling.
