For most beginner and intermediate runners, the Garmin Forerunner 165 is the strongest entry-level running watch you can buy right now. At $249.99 (or $299.99 for the Music version), it brings a bright AMOLED touchscreen, Garmin’s core training tools, and multi-day battery life down to a price that used to get you a much more basic device. This review is based on Garmin’s official specifications, published expert reviews, and aggregated user feedback — not hands-on lab testing — and it covers what the 165 does well, where it cuts corners, and when it’s worth stepping up to the Forerunner 265.
[[AFFDISCLOSURE]]
What is the Garmin Forerunner 165?
Launched in February 2024, the Forerunner 165 sits at the bottom of Garmin’s dedicated running lineup, below the Forerunner 265 and 965. It replaced the aging Forerunner 55 as the sensible starting point, and the headline upgrade is the screen: a 1.2-inch, 390 x 390 AMOLED display with touch input plus Garmin’s familiar five-button layout. The single 43mm case size weighs about 39 grams, so it disappears on the wrist during long runs and sleep.
The 5 ATM water rating means it’s fine for pool swimming and showers — see our guide to water-resistance ratings for what that actually covers. The optical heart rate sensor is Garmin’s fourth-generation Elevate unit, the same family used in far more expensive Garmin watches, and it also drives SpO2 (Pulse Ox) readings and overnight HRV tracking.
Training features: the real reason to buy one
Cheap fitness watches record runs; the Forerunner 165 helps you train. According to Garmin’s spec sheet, it includes almost all of the coaching features that matter for someone building toward a 5K, half marathon, or first marathon:
- Daily suggested workouts that adapt to your recent training and recovery, plus free Garmin Coach training plans synced from the Connect app.
- VO2 max estimates and race predictions for 5K through marathon distances.
- PacePro pacing guidance for race day, including grade-adjusted targets on courses you load onto the watch.
- Recovery time, HRV status, and sleep scoring, summarized each morning in Garmin’s Morning Report.
- Body Battery, Garmin’s readout of your energy reserves based on heart rate variability, stress, and sleep.
Published reviews from outlets such as DC Rainmaker consistently note that GPS and heart-rate accuracy on the 165 are very good for the class, even though it uses standard multi-GNSS (GPS, GLONASS, Galileo) rather than the dual-band positioning found on pricier models. For most road running, user feedback suggests the difference is minor; it matters more in dense cities or canyons. Sleep tracking includes stages and nap detection — our explainer on how accurately smartwatches track sleep stages covers the caveats that apply to every wrist-based device, Garmin included.
Display, battery life, and everyday use
The AMOLED panel is the feature that makes the 165 feel modern. It’s sharp, colorful, and easy to read in sunlight, where older transflective Garmin displays looked dated indoors. The trade-off is battery: Garmin rates the 165 at up to 11 days in smartwatch mode and around 19 hours of GPS-only activity tracking, which drops if you enable the always-on display. That still comfortably beats an Apple Watch or Galaxy Watch, as we break down in our smartwatch battery life comparison.
As an everyday smartwatch, it covers the basics: notifications, Garmin Pay contactless payments, Connect IQ watch faces and data fields, and safety features like incident detection and LiveTrack when paired with your phone. The Music version adds roughly 4GB of storage (about 500 songs) plus offline playlist support for Spotify, Amazon Music, and Deezer, so you can leave your phone at home with Bluetooth headphones.
What you give up at this price
Garmin protects its more expensive watches with a few deliberate omissions:
- No barometric altimeter. Elevation comes from GPS, which is less precise for hilly training and means no floors-climbed tracking.
- No multi-band GNSS, the higher-accuracy satellite mode on the Forerunner 265 and 965.
- No triathlon multisport mode and a shorter list of activity profiles overall.
- No Training Readiness or Training Status, Garmin’s deeper training-load analytics.
- No onboard maps — you get breadcrumb-style course following, not full navigation.
Forerunner 165 vs. Forerunner 265
| Feature | Forerunner 165 | Forerunner 265 |
|---|---|---|
| Price (launch) | $249.99 / $299.99 Music | $449.99 |
| Display | 1.2″ AMOLED | 1.3″ AMOLED (1.1″ on 265S) |
| GPS | GPS/GLONASS/Galileo | Multi-band with SatIQ |
| Barometric altimeter | No | Yes |
| Triathlon mode | No | Yes |
| Training Readiness | No | Yes |
| Battery (smartwatch) | Up to 11 days | Up to 13 days |
The 265 is the better watch, but it costs $150–200 more. Unless you race triathlons, train heavily on trails, or want Garmin’s full training-load suite, published reviews broadly agree the 165 delivers most of the experience for a lot less money.
Verdict: who should buy the Forerunner 165?
- Best value running watch under $300 for most runners
- AMOLED screen and real coaching features at an entry-level price
- Skip it if you need triathlon mode, maps, or a barometric altimeter
Buy the Forerunner 165 if you run (or run-walk) a few times a week and want structured training guidance, reliable GPS, and a screen you’ll enjoy looking at. It’s also an excellent first “serious” watch for someone graduating from a basic fitness band. Look elsewhere if you’re a triathlete, an ultrarunner who needs maps and longer battery, or a data obsessive who wants Training Readiness.

Frequently asked questions
Is the Garmin Forerunner 165 good for beginners?
Yes — it’s arguably the best beginner running watch available. Daily suggested workouts and Garmin Coach plans tell you exactly what to run each day, and the interface combines a touchscreen with physical buttons, so it’s usable mid-run with sweaty fingers.
Does the Forerunner 165 have music storage?
Only the Forerunner 165 Music ($299.99) stores music on the watch, with about 4GB of space and offline support for Spotify, Amazon Music, and Deezer. The standard $249.99 model can control phone playback but not store songs.
Can the Forerunner 165 measure blood oxygen and sleep?
Yes. It includes a Pulse Ox sensor for SpO2 readings and full sleep tracking with stages, sleep score, and HRV status. As with all wrist wearables, treat these as wellness estimates, not medical data — see our guide to SpO2 accuracy on smartwatches.
How long does the Forerunner 165 battery last?
Garmin rates it at up to 11 days in smartwatch mode with the gesture-based display, or roughly 19 hours of continuous GPS activity. Enabling the always-on screen cuts smartwatch battery life to a few days.
