Garmin Forerunner 255 Review
Bottom Line
Choose the Forerunner 255 for accurate GPS, long battery life, comfort, and serious run or triathlon training. Skip it if you want rich smartwatch apps, calls, a touchscreen AMOLED display, or full mapping.
Best for
Best for runners, triathletes, and fitness-focused users who will use GPS accuracy, coaching, recovery metrics, and long battery life. It especially fits people who prefer physical buttons and outdoor readability over a lifestyle-watch interface.
Not for
Not for shoppers who mainly want a rich smartwatch with calls, voice features, a touchscreen AMOLED display, full mapping, or a broad app experience. It may also be more watch than casual activity trackers need.
Verdict
Reviewer evidence frames the Garmin Forerunner 255 as a training-first watch that pushes midrange running watches closer to premium sports models. Across reviews, GPS accuracy, heart-rate performance, battery life, comfort, size choices, multisport support, coaching, recovery metrics, and Garmin Connect depth are recurring strengths. The main tradeoff is that it behaves more like a serious fitness tool than a lifestyle smartwatch: reviewers repeatedly note no touchscreen, a less flashy MIP display, limited call handling, proprietary charging, modest smart features, and missing higher-end tools like Training Readiness or full mapping. For athletes who will wear it day and night and use the training data, the evidence is highly favorable; for casual smartwatch shoppers, its strengths may feel specialized.
