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 offline 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 is doing four things the PACE 4 cannot: full offline maps with turn-by-turn routing, a medically certified wrist ECG, a dual white-and-red LED flashlight, and an on-board speaker and microphone for calls.[1][2] 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 full offline 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 offline 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?
No. The Forerunner 970 has full offline TopoActive maps with turn-by-turn navigation; the PACE 4 offers breadcrumb navigation and route files created in the COROS app, not full on-watch maps.[1][3]
Is the Garmin Forerunner 970 worth three times the price?
Only if you use the features the PACE 4 lacks: full offline 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]
