Coros Pace 3

The Coros Pace 3 and the Garmin Forerunner 255 are both feature-rich running watches, but they present a few notable distinctions, especially concerning tracking depth and physical specifications. A significant advantage for the Forerunner 255 lies in its expanded health and activity tracking, including dedicated features like Training Programming and Stress level monitoring, which are absent from the Pace 3's listed capabilities. However, the Pace 3 is substantially lighter, weighing only 30g compared to the Forerunner 255's 49g, which is a key consideration for runners prioritizing minimal bulk. Furthermore, the Forerunner 255 utilizes the more durable Gorilla Glass for its screen protection, whereas the Pace 3 features Mineral glass. While both offer excellent GPS capabilities and similar running battery life, the Garmin targets users seeking deeper analytical metrics, while the Coros appeals to those demanding an extremely lightweight device.
