Why We Like The Forerunner 255

When we’re ready to take our running and training efforts to the next level, we count on the Forerunner 255 to provide the information we need to optimize our intensity and recovery. This smartwatch is built for running, with integrated technology to help manage our pace, optimize calorie intake, and even dial in our race training. It’s packed with features for other disciplines too, with an integrated GPS, submersible design, and even preset profiles for skiing and snowboarding.
