Garmin Forerunner 170 or COROS PACE 4 Standard: which mid-range running watch fits your training priorities? Two training approaches, two ecosystems.

Short answer

There is no universal winner: the right choice follows your priorities. The 170 leans on the Garmin ecosystem (daily suggested workouts, Garmin Coach per the sheet) and a 1.2-inch AMOLED touchscreen; the PACE 4 Standard leans on the COROS app (planning, load, recovery), a light format and a polymer bezel. Pricing can change, so check both before deciding.

Key differences

  • Garmin training approach: daily suggested workouts and Garmin Coach per the manufacturer sheet; a broad ecosystem of accessories and apps.
  • COROS training approach: planning, load and recovery indicators in the COROS app per the sheet; a training-data-oriented ecosystem.
  • Display/interface: the 170 has a 1.2-inch AMOLED touchscreen; the PACE 4 Standard adds the newer display/interface package documented in its product evidence — compare the sheets for details.
  • GPS/navigation: both record routes via GPS; no full mapping is announced for these models per the sheets.
  • Announced battery: compare both manufacturer sheets; battery life varies with use (GPS, display).
  • Music: neither model compared here carries onboard music per the sheets; music is managed from the phone.
  • Physical format: both aim for comfortable wrist wear; the PACE 4 Standard emphasizes lightness; the 170 has a 43 mm case.
