Garmin Forerunner 170 Offers Enhanced Features Over Forerunner 165

Garmin's latest entry-level running watch, the Forerunner 170, brings notable enhancements over its predecessor, the Forerunner 165. Priced at $299 for the standard model and $349 for the music version, the Forerunner 170 offers a more sophisticated user experience and advanced training features, catering to both casual runners and serious athletes alike.

In 2026, Garmin continues to expand its Forerunner line, which now includes three new models at the entry level. The Forerunner 70 replaces the Forerunner 55, while the Forerunner 170 and its music-capable variant replace the Forerunner 165. The price increase is significant, with the Forerunner 165 priced at $249 and $299 for the music version. Given the regular discounts on the Forerunner 165, potential buyers might find themselves paying considerably more for the new model.

Design and User Interface

Both the Forerunner 165 and 170 sport a similar design, featuring lightweight plastic cases, a 1.2-inch AMOLED touchscreen, and a five-button layout. However, the Forerunner 170 weighs slightly more at 41g compared to the 39g of the 165. The two models share a water resistance rating of 5ATM and a GPS chipset, ensuring reliable tracking in various conditions.

A key advancement in the Forerunner 170 is the introduction of a gyroscope sensor, which enhances movement tracking for a more accurate workout experience. The user interface has received a substantial update, incorporating features from more advanced models like the Forerunner 570 and 970. Notable additions include battery and sports scores widgets, a calculator app, and Garmin's Lifestyle Logging and Health Status features.

Enhanced Sports Tracking and Training Analysis

The Forerunner 170 significantly outshines the 165 in sports tracking and training analysis. The new model includes advanced metrics such as training readiness, training status, and acute load, which were previously available only in higher-end models. This makes the Forerunner 170 a more capable tool for dedicated runners seeking detailed feedback on their performance.

In addition to these metrics, the Forerunner 170 offers a wider array of sports modes, including options for winter and team sports, which were lacking in the 165. New running statistics, such as Grade Adjusted Pace, assist runners in evaluating their effort on inclines. Garmin has also introduced a Quick Workout feature that allows users to create tailored workout sessions based on desired intensity and duration.

GPS and Heart Rate Monitoring

While neither the Forerunner 165 nor the 170 features multi-band GPS tracking—Garmin's most advanced GPS technology—both models deliver solid performance in terms of accuracy. In a comparative 10K run, both watches provided precise readings, aligning closely with the more expensive Forerunner 970.

Both models utilize the Elevate Gen 4 optical heart rate sensor, which has proven reliable in previous tests. Early evaluations of the Forerunner 170 show that it maintains accuracy comparable to a chest strap, often considered the gold standard for heart rate monitoring during runs.

Verdict: Is the Upgrade Worth It?

The Garmin Forerunner 170 offers substantial improvements over the Forerunner 165, particularly in software features that enhance everyday usability and training support. However, for many, the core functionalities of the Forerunner 165 remain appealing, especially given its lower price point. The decision to upgrade hinges on the value placed on the new features and ongoing software updates the Forerunner 170 will receive.

For those who prioritize advanced training analysis and a richer user experience, the Forerunner 170 justifies the additional cost. However, for budget-conscious runners, the Forerunner 165 continues to be a strong contender, delivering excellent performance without the premium price tag.
