The Garmin Forerunner 165 and the COROS Pace 3 are two GPS running watches built around structured training. This comparison helps you see which one fits your use best.

This comparison covers the standard (non-Music) Garmin Forerunner 165; the COROS Pace 3 colourway can vary by market.

This comparison is based on documented sources only: the published product sheets and the manufacturer-announced specifications. We have not run independent tests. Current pricing can change, so check both before deciding.

Strengths

  • Garmin Forerunner 165: 43 mm AMOLED display built for running
  • Garmin training features: daily suggested workouts and Garmin Coach, according to the manufacturer sheet
  • Standard model: no onboard music storage, music is controlled from your phone

Limitations

  • No standalone music playback on the watch
  • Announced battery life varies with use (GPS, display): check the manufacturer sheet
  • Some features from higher Garmin ranges are not included
  • The 43 mm case does not suit every wrist: check the fit

Strengths

  • COROS Pace 3: light GPS running watch designed for long wear
  • Battery life is the central claim on the manufacturer sheet, with several GPS modes
  • COROS training ecosystem: planning, load and recovery via the app

Limitations

  • No onboard mapping or music according to the manufacturer sheet
  • Real battery life depends on use (GPS, backlight)
  • The colourway varies by market: it does not change the features

In summary

The Garmin Forerunner 165 focuses on the AMOLED display and Garmin's training ecosystem, in a 43 mm format, without onboard music storage. The COROS Pace 3 focuses on lightness and announced battery life, with the COROS training app, but without onboard mapping or music.

Verdict

Choose the Forerunner 165 if the AMOLED display and Garmin's training ecosystem matter more to you. Choose the Pace 3 if low weight and a battery-focused design are higher priorities. Neither watch is universally better — they answer to different priorities. Our take does not replace checking the current prices and the official specification sheets.
