Garmin Forerunner 970 Review: Premium Runner's Watch Tested

What It Is

The Garmin Forerunner 970 sits at the top of Garmin's running-focused lineup, priced at around £599.90 in the UK. It targets serious runners and multisport athletes who want deep training metrics, solid GPS performance, and the full Garmin ecosystem. At this price, it goes head-to-head with the Amazfit Cheetah 2 Ultra and trades blows with the Apple Watch Ultra 3 in controlled testing. This is not a watch for casual joggers or people who want a smartwatch that occasionally tracks a run.

Key Specs

• GPS chipset: Multi-band GNSS (satellite-based positioning)
• Battery life: Extended GPS mode available; firmware 16.28 added battery manager insights for better runtime visibility
• Sensors: Wrist optical PPG for heart rate and HRV (beat-to-beat intervals derived from blood volume changes), SpO2 (optical blood oxygen), skin temperature, barometric altimeter (air pressure-based altitude calculation)
• Display: Touchscreen (touch sensitivity issues reported in early firmware builds)
• Water resistance: Suitable for swimming and multisport use
• Connectivity: Connect IQ app support confirmed in real-world testing

Performance in the Real World

GPS accuracy is the headline story, and it is a complicated one. A controlled track test put the Forerunner 970 up against the Apple Watch Ultra 3, Amazfit Balance 2, and Huawei Runner 2. The result? The Forerunner 970 did not win. Being beaten on a track test by competitors at lower price points is a meaningful finding for a watch at this tier. The Apple Watch Ultra 3 also failed in that same test, particularly in track mode, which is a separate embarrassment for Apple, but it does not excuse Garmin here.

Heart rate accuracy in real workouts tells a better story. In a HYROX simulation session, the Forerunner 970 was used as the reference device alongside a Whoop MG and the Amazfit Balance 3. The Balance 3 showed around 3 bpm high bias with one cadence lock incident, while the 970 performed as the benchmark. That suggests optical PPG performance during high-intensity efforts is solid, though the sources do not give a precise error figure for the 970 itself in that session.

Connect IQ integration works cleanly in practice. A test using the hDrop sweat sensor Connect IQ data field on the 970 ran without issues, even if the hDrop hardware itself overestimated fluid loss by 51% against body weight change at 27 degrees Celsius. That is the sensor's problem, not Garmin's, and it is a good sign that the platform handles third-party data fields without friction.

Sleep tracking, HRV logging, elevation, metronome, touchscreen responsiveness, and brightness have all appeared in bug reports across two separate fix file issues (weeks ending 17 July and 7 August 2026). Rowing activity resets and alarm volume spikes also showed up. Some of these are firmware-level issues that get patched, and version 16.28 brought 12 new features including smart notification delays and multisport profile expansions alongside bug fixes. But the volume of reported faults in a short window is worth flagging. Early adopters had a rougher experience than they should have at this price point.

The app ecosystem remains Garmin's strongest card. Garmin Connect is mature, Garmin Coach integration works (though rest day handling has had quirks), and the Connect IQ store gives access to third-party data fields and watch faces that competitors simply cannot match in depth.

Who It's For / Who Should Skip It

Buy the Forerunner 970 if you are a runner or triathlete who lives inside the Garmin ecosystem, wants deep training load metrics, and values long-term firmware support and a large third-party app library. If you already own a Garmin and are upgrading from a Forerunner 265 or 955, the feature jump is real.

Skip it if GPS accuracy is your absolute top priority. The track test result is hard to ignore for people who care about precise distance and pace data. Also skip it if you are budget-conscious: the Amazfit Cheetah 2 Ultra hits the same price with an 85% GPS accuracy score in trail testing and a 55-hour projected GPS battery, which makes the value comparison uncomfortable for Garmin. If you are not already invested in Garmin's ecosystem, the case for paying this much gets thinner.

Verdict

The Forerunner 970 is a capable, feature-rich running watch let down by a GPS accuracy result that should not happen at this price, and a firmware launch period with too many rough edges. It is worth buying if Garmin's ecosystem is your home base, but go in with eyes open: the Amazfit Cheetah 2 Ultra is a real alternative at the same price, and Garmin needs to tighten up both GPS performance and software stability to justify the premium without hesitation.
