Premium Garmin watches like the Fenix 8 Pro grab headlines, but on the trails and roads near my home, I see far more entry-level Forerunners strapped to fellow runners’ wrists. That makes the arrival of the Garmin Forerunner 170 a genuinely important release for anyone serious about training without spending a fortune. After two weeks of testing the Music model, I have a clear picture of where this watch shines and where it cuts corners.
Garmin Forerunner 170 Review: Price and Availability
Garmin launched the Forerunner 170 in May 2026, positioning it as the mid-range option alongside the cheaper Forerunner 70. The standard model costs $299 in the United States and £259 in the United Kingdom. If you want onboard music storage — the Music model — the price climbs to $349 or £299. That represents a $50 increase over the previous-generation Forerunner 165 Music, a jump that raises eyebrows given the modest hardware changes.
For comparison, the Forerunner 70 lists at $249 / £219 but lacks several sensors and smart features found on the 170. Main competitors include the Coros Pace 4 and Suunto Run, both priced at $249. Those watches offer similar form factors and AMOLED displays, making the Forerunner 170’s higher starting price a point worth examining closely in this garmin forerunner 170 review.
Garmin Forerunner 170 Review: Design and Display
The Forerunner 170 measures just 42.6mm across and 11.9mm thick, with a weight of only 41 grams. That makes it one of the lightest GPS running watches available. I found it virtually unnoticeable during runs — it never snagged on jacket cuffs or pressed uncomfortably against my wrist bone during sleep tracking.
Garmin sticks with its classic five-button layout, which remains a blessing for runners with sweaty fingers. The touchscreen works smoothly for quick menu swipes, but physical buttons let you start a workout, mark laps, or pause without glancing at the display. The 1.2-inch AMOLED panel has a 390 x 390 pixel resolution. It is smaller than screens on the Forerunner 265 or Fenix series, but I had no trouble reading five data fields simultaneously, even in direct sunlight.
One notable omission: Garmin chose the Elevate Gen 4 optical heart rate sensor instead of the newer Gen 5 found on pricier models. The Gen 4 lacks ECG capability and skin temperature monitoring. In my experience, the Gen 4 tends to lag behind the Gen 5 in capturing rapid heart rate changes during interval workouts, though daily resting readings remain consistent.
On the positive side, the Forerunner 170 includes a barometer, altimeter, and gyroscope — sensors absent from the cheaper Forerunner 70. These additions noticeably improved elevation tracking accuracy during my hilly trail runs. The watch also pairs with external sensors via Bluetooth and ANT+, including chest straps and cycling power meters, a feature the Forerunner 70 omits entirely.
Garmin Forerunner 170 Review: Sports Tracking and Training Analysis
This is where the Forerunner 170 pulls away from its budget sibling. Garmin has ported several advanced training metrics down from the Forerunner 965 and 970 series. You get Training Status, which tracks whether your fitness is improving, maintaining, or declining over weeks. Training Readiness offers a daily score from 1 to 100 based on sleep quality, stress levels, and recent exercise load. Training Load analysis breaks your efforts into aerobic and anaerobic categories, helping you balance hard and easy days.
As a marathon runner, I found these tools genuinely useful. Training Readiness gave me a clear reason to skip a run when my score sat at 32 after a poor night’s sleep. Over two weeks, the watch correctly identified my increasing aerobic load as I built mileage. The only missing metric is Running Tolerance, a feature reserved for the Forerunner 970 that tracks how well your body handles cumulative strain on bones and joints. For most runners, that exclusion is not a dealbreaker.

The Forerunner 170 adds many new sport modes beyond running, including winter sports like cross-country skiing, team sports like soccer, and racket sports like tennis. GPS accuracy proved reliable during my suburban routes, with typical deviation under 5 metres compared to a known measured course. Elevation data from the barometer smoothed out jagged plots that often appear on phones or watches without pressure sensors.
Heart rate accuracy during steady-state runs stayed within 3 beats per minute of a chest strap. During a 400-metre interval session, the Gen 4 sensor sometimes missed the peak heart rate by 6 to 8 beats, which means interval pacing might be slightly off if you rely solely on wrist-based data. For most daily training, however, the readings are adequate.
Garmin Forerunner 170 Review: Battery Life and Connectivity
Garmin rates the Forerunner 170 at up to 10 days in smartwatch mode and 20 hours of continuous GPS tracking with all systems enabled and the always-on display active. In real-world testing with one hour of GPS activity per day, nightly sleep tracking, and notifications enabled, I got about 8 full days before the battery dipped below 20%. That matches the Forerunner 165 but falls short of the Coros Pace 4, which manages 24 hours of GPS and 19 days of watch mode for the same price.
The Music model contains 4GB of internal storage, enough for roughly 400 songs if you use Spotify offline playlists. Transferring music via Wi-Fi takes about 8 minutes for a 200-song playlist. Bluetooth earbuds paired quickly and maintained a stable connection within 10 metres.
Connectivity options include Bluetooth, ANT+, and Wi-Fi for automatic activity uploads. The watch supports Garmin Pay for contactless payments, a feature absent on the Forerunner 165. Smart notifications work reliably, though you cannot reply to messages from the watch.
Garmin Forerunner 170 Review: 5 Pros and 5 Cons
Pros
- Lightweight and comfortable design – At 41 grams, the watch disappears on the wrist. It is ideal for all-day wear and sleep tracking without irritation.
- Advanced training metrics at a lower price – Training Status, Training Readiness, and Training Load analysis bring premium features to a mid-range watch, helping runners plan smarter.
- Barometer and altimeter for accurate elevation – These sensors, missing on the cheaper Forerunner 70, deliver reliable ascent and descent data for trail runners and hikers.
- Solid display and button control – The AMOLED screen is bright and readable, while the five-button layout offers reliable operation in rain or with gloves.
- Garmin Pay and music storage options – Contactless payments and offline music add everyday convenience that many competitors at this price skip.
Cons
- Higher price than key rivals – At $299/$349, the Forerunner 170 costs $50 more than the Coros Pace 4 and Suunto Run, which offer similar specs and longer battery life.
- Gen 4 heart rate sensor limitations – The absence of the Elevate Gen 5 sensor means no ECG, no skin temperature, and slightly worse interval tracking accuracy compared to newer Garmin models.
- Battery life lags behind competitors – 10 days watch mode and 20 hours GPS are adequate but trail runners and ultramarathoners may prefer the 19-day/24-hour numbers from the Coros Pace 4.
- No Running Tolerance metric – Runners looking for the most advanced injury prevention data will need to step up to the Forerunner 970 or Fenix series.
- Music model price increase over predecessor – The $50 jump from the Forerunner 165 Music feels steep, given that the core hardware upgrades are incremental.
Garmin Forerunner 170 Review: Final Thoughts
The Garmin Forerunner 170 strikes a careful balance between affordability and advanced features. It brings training metrics that genuinely help runners manage their workload — something the Forerunner 165 could not do — while keeping the weight and size that make everyday wear comfortable. The higher price compared to the Coros Pace 4 and Suunto Run demands justification, and the Gen 4 heart rate sensor shows its age in high-intensity intervals. For runners who value Garmin’s ecosystem, the five-button interface, and the added sensors for elevation tracking, this garmin forerunner 170 review concludes that the watch is a solid investment for improving training structure without breaking the bank. Casual joggers or health-focused users may be better served by the cheaper Forerunner 70, but anyone training for a goal race will find the extra data worth the premium.
