Forerunner 165 Black | Slate Grey

The Garmin Forerunner 165 is a purpose-built running smartwatch designed for athletes who want clear data, smart training guidance, and long battery life—without paying flagship prices. The bright 1.2" AMOLED display stays easy to read in all conditions, while adaptive training plans and recovery insights help you train smarter, not harder.

Built with runners in mind, Forerunner 165 tracks pace, distance, cadence, heart rate, VO₂ max, and recovery time using multi-band GNSS support. Daily Suggested Workouts adjust automatically based on performance and recovery, making it ideal for structured training or consistent everyday runs.

Off the run, it functions as a full-featured smartwatch with sleep tracking, Body Battery™, stress monitoring, Garmin Pay™, smart notifications, and up to 11 days of battery life in smartwatch mode. Lightweight, comfortable, and durable, it’s equally suited to race day, training blocks, and daily wear.

The Black | Slate Grey colourway keeps things understated and versatile—clean enough for everyday use, serious enough for race day.
