Forerunner 165 vs 170: What This Comparison Is About
Forerunner 165 vs 170 is a comparison between two mid-tier Garmin running watches that share similar hardware but differ in advanced training metrics, especially the training readiness score, helping runners decide whether the newer model’s recovery and load features justify an upgrade for their specific training goals. Both watches look and feel alike, with 1.2-inch AMOLED touchscreens, five buttons, and lightweight plastic cases that sit comfortably on the wrist for daily wear and long runs. They also share the same GPS and optical heart rate sensors, so you will not see a big leap in core tracking accuracy by moving to the 170. Where the 170 steps ahead is in software: it adds the training readiness score, training status, and acute load analysis to the same sensor package, putting more coaching-style insight on your wrist without changing the basic running experience.
Training Readiness Score: The Real Difference
The main reason to consider the Forerunner 170 is its training readiness score and related analytics. The 170 adds Training Readiness, Training Status, and Acute Load to this price tier, features that previously appeared on higher-end Garmin models. These metrics pull together sleep, recent load, and recovery trends into a simple daily score so you can judge whether to push, hold steady, or back off. According to Lifehacker’s comparison, the author is “a pretty big fan of Training Readiness, which gives you a daily score to help you decide how hard to push in a workout.” For runners prone to stacking hard sessions or guessing recovery needs, this can prevent overtraining and guide smarter periodization. If you prefer a watch that offers clear, actionable guidance instead of raw numbers alone, the 170’s training readiness tools may feel like a meaningful upgrade over the 165.
Running Economy Tracking: Strengths Both Watches Share
If you care about running economy tracking and detailed form analysis, both the Forerunner 165 and 170 can play in the same league when paired with the right accessories. Garmin’s running economy score is based on heart rate, speed, and running dynamics such as step speed loss, which the company defines as the drop in forward speed from foot strike to minimum speed during ground contact. In a Lifehacker test, one runner’s half-marathon data showed an average step speed loss of 8.2 cm/s and an SSL percentage of 2.85%, illustrating how small braking forces add up over a race. These insights are not watch-specific; they depend on compatible sensors like the HRM-600 and the Garmin Connect app’s analysis. That means both 165 and 170 can give serious runners the same deep performance metrics for form efficiency once the extra heart rate monitor is in the mix.
Price Gap and Value for Data-Focused Runners
Cost is where the Forerunner 165 vs 170 decision becomes tricky for data-focused runners. The Forerunner 170 costs USD 299 (approx. RM1,380), compared with USD 249 (approx. RM1,150) for the 165 at full price, and the music versions follow the same USD 50 (approx. RM230) difference. Lifehacker notes that “the Forerunner 165 goes on sale constantly,” which often widens the real-world gap to closer to USD 100 (approx. RM460). Since both watches share GPS, optical heart rate sensors, and can tap into the same running economy tracking with accessories, you are paying that difference mainly for training readiness, training status, acute load, a gyroscope, and some small widget upgrades. If you thrive on detailed guidance and load management, the extra spend on the 170 may feel justified; if you mainly want accurate tracking and economy data, a discounted 165 is tough to beat.
Garmin Upgrade Guide: Who Should Switch to the 170?
To decide on upgrading, think about how you train and how much coaching you want from your watch. Choose the Forerunner 170 if you rely on metrics to structure your week, want training readiness and training status on your wrist, and like features such as Quick Workouts that let you set a session by effort level and duration rather than designing intervals from scratch. The added gyroscope helps refine movement tracking but is secondary to the new recovery metrics. Stick with, or buy, the Forerunner 165 if you are budget-conscious, can find it on sale, and are happy to interpret raw data yourself rather than follow a daily readiness score. Since both support running economy tracking with the right heart rate monitor, your upgrade decision comes down to this: do you want more numbers, or more guidance on what to do with them?
