GPS Running Smartwatch

For runners who want more data without buying a different watch in two years.

The Forerunner 170 is the watch you reach for when you've outrun your first fitness tracker. It costs $50 more than Garmin's entry-level Forerunner 70 — and that $50 buys you the full sensor stack a serious runner actually uses: barometric altimeter, three-axis compass, gyroscope, thermometer, and tap-to-pay.

You still get the same 1.2" AMOLED touchscreen, the same triple-system GPS (GPS + GLONASS + Galileo), the same Garmin Coach adaptive training plans, the same Training Readiness score that tells you each morning whether to push or recover. What changes is what the watch can measure while you're running — elevation gain on real climbs instead of estimated from GPS, true compass heading when you're navigating, body-temperature trends across a training block. Buy your post-workout coffee from your wrist with Garmin Pay.
