Expert opinion

The Garmin Forerunner 170 is the plus version of the company’s entry level option, introducing modern hardware and major firmware upgrades to Garmin’s budget tier.

The Forerunner 170 succeeds the Forerunner 165 and sits above the Forerunner 70 in Garmin’s 2026 entry lineup. It is a software-led upgrade: the case, the 1.2 inch AMOLED display and the Elevate Gen 4 sensor carry over from the 165, while the modern Garmin software stack arrives, Training Readiness, Training Status, wrist-based Running Power and Dynamics, Garmin Cycling Coach and Quick Workouts. Over the Forerunner 70 it adds a barometric altimeter, compass, gyroscope and thermometer, Garmin Pay, open water swimming, and cycling power-meter support. The Music edition adds 4GB of onboard storage for offline playback. Battery life is up to 10 days in smartwatch mode and 17 hours in GPS, slightly behind the 165 in some modes. The 43mm case is small.
