TL;DR
- Buy the COROS PACE 4 for the best battery-and-price value with subscription-free training; buy the Garmin Forerunner 970 for maps, ECG, a flashlight, and the deepest ecosystem. They are not really rivals on price: the 970 is $749.99 and the PACE 4 is $249.
- Both carry dual-frequency (multiband) GNSS, so positioning hardware is close; the gap is features, not satellites.[1][3]
- Battery favours COROS: 41 hours GPS and 19 days daily on the PACE 4, against up to 26 hours GPS-only and 15 days on the 970.[2][3]
- Neither needs a subscription. Garmin's core metrics are free; Connect+ is optional. COROS has no paid tier.[1][3]
The Forerunner 970 is Garmin's flagship running watch and the PACE 4 is COROS's value-leading running watch, so this matchup is really about how much watch you need. Both have AMOLED screens and multiband GPS; the 970 then adds mature routable maps, a wrist ECG, a built-in flashlight, and a speaker, while the PACE 4 wins on weight, battery, and a price a third of the 970's.

Battery: COROS wins, but both clear a marathon easily
The PACE 4 runs up to 41 hours of GPS and 19 days of daily use; the Forerunner 970 manages up to 26 hours GPS-only and 15 days, dropping to about 21 hours in its most accurate multi-band mode.[2][3] Both easily survive any marathon and most 100 km efforts. The COROS only pulls clearly ahead for multi-day adventures or if you simply hate charging.
GPS: a near wash on hardware
Both watches use dual-frequency (multiband) GNSS, so the budget-tier GPS gap does not exist here. The 970 layers Garmin's SatIQ on top, which adaptively switches frequencies to save battery, and the PACE 4 runs dual-frequency across all systems.[1][3] DC Rainmaker's testing puts the PACE 4's GPS in the same league as Garmin's flagship at a quarter of the price.[4]
Where the 970 earns its premium
The Forerunner 970 does four things the PACE 4 cannot match: full TopoActive maps with turn-by-turn routing (the PACE 4's maps arrived as a beta in September 2026), an FDA-cleared wrist ECG app, a dual white-and-red LED flashlight, and an on-board speaker and microphone for calls.[1][2][6] It also uses Garmin's newer Elevate Gen 5 optical sensor and a sapphire lens.[2] If maps and ECG matter to you, the PACE 4 is not a substitute at any price. Worth noting on heart rate: both read from the wrist and trail an ECG chest strap during intervals, so neither optical sensor settles the choice, and zone-precise runners should add a strap to whichever they buy (the studies are here).[5]
Which one is right for you
- Best value, longest battery, lightest, no subscription: COROS PACE 4.
- Maps, ECG, flashlight, speaker, deepest ecosystem: Garmin Forerunner 970.
- Trail navigation off a planned route: the 970, for mature routable maps.
- First serious running watch on a budget: PACE 4, easily.
Here is where it lands: most runners are better served by the COROS PACE 4, which matches the 970 on multiband GPS, beats it on battery and weight, and costs $500 less. Pay the Garmin premium only if you genuinely use routable on-watch maps, want wrist ECG, or are committed to the Garmin ecosystem. After you choose, set your training zones from a measured maximum with the Heart Rate Zone Calculator, and for the brand-level call read Garmin vs COROS 2026.

FAQ
Is the COROS PACE 4 GPS as accurate as the Garmin Forerunner 970?
Both use dual-frequency (multiband) GNSS, and independent review testing places the PACE 4's GPS in the same league as Garmin's flagship. The hardware gap is small; the 970's advantages are maps, ECG, and ecosystem, not positioning accuracy.[3][4]
Does the COROS PACE 4 have maps like the Forerunner 970?
Since September 2026, in beta. A COROS update added downloadable global maps with street and trail names to the PACE 4, the same maps the APEX 4 and PACE Pro use. The Forerunner 970's TopoActive maps are more mature and route turn-by-turn on the watch.[1][6]
Is the Garmin Forerunner 970 worth three times the price?
Only if you use what the PACE 4 lacks or does less well: mature routable maps, a wrist ECG, a flashlight, and the larger Garmin ecosystem. On GPS and battery the much cheaper PACE 4 matches or beats it.[1][3]
Do either of them need a subscription?
No. COROS has no paid tier, and Garmin's core training metrics are free on the 970; Garmin Connect+ is optional.[1][3]
