Garmin Forerunner 70 vs 170 2026: Which Budget Running Watch Should You Buy?
Garmin just reset the entry-level running watch market. The new Forerunner 70 ($249) and Forerunner 170($299) pack AMOLED displays, Garmin's complete physiological training stack, and multi-day battery life into sub-$350 watches. Early reviews are calling them the best value Garmin has ever shipped. But which one should you buy? We break down every difference that matters.
Best Value
Forerunner 70 at $249 — full training stack, 13-day battery, AMOLED. Hard to beat for road runners.
Best for Trail
Forerunner 170 at $299 — adds altimeter, compass, and temperature sensor for off-road running.
Best All-Rounder
Forerunner 170 Music at $349 — adds offline Spotify and Garmin Pay NFC.
What Do the Forerunner 70 and 170 Have in Common?
Before diving into differences, it's worth noting how much these watches share. Both the Forerunner 70 and 170 have:
- 1.2-inch AMOLED touchscreen with 5-button physical layout
- Garmin Elevate Gen4 optical heart rate sensor
- Full GNSS support (GPS, GLONASS, Galileo) with SatIQ
- Training Readiness, Training Status, and HRV Status
- VO2 Max, Training Load, and wrist-based running power
- Running dynamics (cadence, ground contact time, stride length)
- Daily suggested workouts and Garmin Coach plans
- Water resistance: 5 ATM (50 meters)
- Case size: 43mm with identical dimensions
This shared feature set is what makes both watches exceptional value. Garmin's full physiological tracking stack — previously exclusive to $400+ watches like the Venu 4 and Forerunner 265 — now starts at $249.
Where Does the Forerunner 170 Justify Its $50 Premium?
The $50 gap between the Forerunner 70 and 170 buys you four specific hardware upgrades:
- Barometric altimeter: Accurate elevation tracking for hill workouts and trail running. The Forerunner 70 relies on GPS-only elevation, which is less precise.
- Magnetic compass: Useful for navigation and orientation when you're off the beaten path.
- Gyroscope: Enables more accurate wrist-based motion detection and gesture controls.
- Temperature sensor: Monitors ambient temperature, which affects training performance and acclimatization insights.
The trade-off? Battery life. The Forerunner 70 lasts up to 13 days in smartwatch mode versus 10 days for the Forerunner 170. Those extra sensors draw power, though both watches still far outlast any Apple Watch or Pixel Watch.
Is the Forerunner 170 Music Worth $100 More Than the 70?
The Forerunner 170 Music ($349) adds two features on top of the standard 170:
- Onboard music storage: Download playlists from Spotify, Amazon Music, or Deezer for phone-free runs with Bluetooth headphones
- Garmin Pay NFC: Contactless payments from your wrist
If you run without your phone and want music, the $100 premium is worth it. If you always carry your phone, save the money and get the standard Forerunner 70 or 170.
How Do They Compare to Apple Watch and Pixel Watch?
The Apple Watch Series 11 at $259 is the closest competitor on price. It wins on smartphone integration, apps, and cellular options — but the Forerunner 70 crushes it for running-specific use:
- Battery: 13 days (Forerunner 70) vs. 18 hours (Apple Watch)
- Training tools: Training Readiness, Garmin Coach, running dynamics (Forerunner) vs. basic workout tracking (Apple Watch)
- GPS accuracy: Multi-band GNSS (Forerunner) vs. single-frequency GPS (Apple Watch)
- Price: $249 (Forerunner 70) vs. $259+ (Apple Watch)
The Google Pixel Watch 3 at $247 is similarly priced but offers only 24-hour battery life. For dedicated runners, the Garmin wins handily. For everyday smartwatch use with occasional running, Apple Watch and Pixel Watch are better choices.
Which Forerunner Should You Buy?
Here's our recommendation based on your running profile:
- Road runners on a budget: Forerunner 70 ($249). You get 95% of the features at the lowest price, plus the longest battery life.
- Trail runners or hikers: Forerunner 170 ($299). The altimeter and compass are essential for off-road navigation and elevation-based training.
- Phone-free runners who want music: Forerunner 170 Music ($349). Offline Spotify and Garmin Pay make it a true standalone device.
- Casual runners who also want a smartwatch: Consider the Apple Watch Series 11 or Pixel Watch 3 instead — they're better general-purpose devices.
