What We Like and What to Consider
Our analysis of official specifications and verified owner reviews surfaces clear strengths alongside a few honest trade-offs.
What We Like
- Brightest AMOLED in this lineup: The display is Garmin’s most vivid yet in a Forerunner, making it easy to read pace and metrics mid-run in direct sunlight.
- Compact 42mm fit: The aluminum bezel is sized specifically for smaller wrists, a detail owners with sub-6-inch wrists consistently highlight in reviews.
- Adaptive Garmin Coach plans: Training plans for both running and triathlons adjust automatically based on your performance and recovery data, not a fixed calendar.
- Wrist-based phone calls: The built-in microphone and speaker let you answer calls and use your smartphone’s voice assistant directly from the watch when paired.
What to Consider
- GPS battery ceiling: At 18 hours in GPS mode, ultra-distance runners logging back-to-back long days may need to recharge mid-event more often than with some rivals.
- Single size option: The 42mm case is purpose-built for smaller wrists, so athletes who prefer a larger display will need to look at other Forerunner models.
- Garmin ecosystem requirement: Garmin Coach plans, morning and evening reports, and voice assistant features all depend on pairing with a compatible smartphone and the Garmin Connect app.
Who Should Buy the Garmin Forerunner 570 (and Who Should Skip It)
This watch is built for a specific type of athlete, and knowing where it fits saves you from a costly return.
- Buy it if you have smaller wrists and want Garmin’s sharpest AMOLED display without wearing an oversized case all day.
- Buy it if you are training for a running race or triathlon and want a coaching plan that adapts to how your body is actually recovering, not just a static schedule.
- Buy it if you want a running watch that doubles as a capable smartwatch, complete with wrist-based phone calls and daily health briefings via morning and evening reports.
- Skip it if you regularly run ultras longer than 18 hours in a single GPS session. A Garmin Forerunner model with extended GPS battery, such as the Forerunner 965, will serve those efforts better.
- Skip it if you are an Apple ecosystem user who relies on deep iPhone integration and watchOS apps. The Apple Watch Series 12 will give you tighter native connectivity with your iPhone.
Final Thoughts
The Garmin Forerunner 570 earns its place as a serious training tool for dedicated runners and triathletes who also happen to have smaller wrists. The single biggest reason to buy it is the combination of Garmin’s brightest AMOLED display, 10-day smartwatch battery, and genuinely adaptive Garmin Coach plans in one compact package. Owners who want to monitor their readiness before each workout can also pair the watch’s data with our running pace calculator to fine-tune race-day targets.
If your priority is the absolute longest GPS recording time for ultra-distance events, a larger Forerunner model with multi-day GPS endurance will be a better fit. Likewise, casual fitness trackers who do not need structured coaching or HRV analysis may find a simpler watch meets their needs at a lower price point.
FAQs
How long does the battery last during a GPS run?
The Garmin Forerunner 570 lasts up to 18 hours in GPS mode. In standard smartwatch mode without active GPS, battery life extends to up to 10 days.
Does the Forerunner 570 work with both iPhone and Android?
Yes, it pairs with both iPhone and Android smartphones via the Garmin Connect app. Features like phone calls from your wrist and voice assistant access depend on your paired phone being nearby and connected.
What health metrics does the Forerunner 570 track daily?
The watch tracks HRV status, VO2 max, training readiness, training load, and sleep quality, then surfaces them in a morning report and an evening report each day. If you want to put those recovery numbers to work, our sleep calculator can help you find an optimal bedtime to support your training schedule.
Is the 42mm case a good fit if I have a larger wrist?
The 42mm aluminum case is designed specifically for smaller wrists, so athletes with larger wrists may find it feels undersized. Garmin offers larger Forerunner models in the same family that may be a more comfortable fit for bigger wrists.
