Garmin Forerunner 165 vs Garmin vívoactive 5

Both are 42-43mm AMOLED Garmin watches with built-in GPS and up to 11 days of battery, so the split is training depth versus everyday versatility. The Forerunner 165 is the running tool: Garmin Coach plans, race predictions, VO2 max, training effect and a morning report aimed at people chasing a time. The vivoactive 5 is the generalist: music storage, Garmin Pay, sleep coaching, meditation, wheelchair mode and 1,600+ exercises, but no race-pace tooling. Owners rate the Forerunner highly for its display and battery; vivoactive buyers like the sleep and Body Battery insights and call it a bit clunky on small wrists.

• Choose the Forerunner 165 if you run regularly and want structured plans, race predictions and recovery metrics built around running.
• Choose the vivoactive 5 if you want one watch for the gym, sleep, music and contactless payments more than race training.
