The Coros Pace 4 is one of the best running watches we’ve tested, offering accurate tracking in a lightweight, comfortable design that now sports a bright AMOLED display, which is the main upgrade on the Coros Pace 3.
It’s also good value, and has enough features to satisfy runners of all levels who prefer a smaller watch, including offline maps. The Pace 4’s main competition comes from the Garmin Forerunner 70 and Garmin Forerunner 170 watches, which are the entry-level options in Garmin’s line-up, and the Suunto Run 2.

Coros Pace 4 review
Below you’ll find videos for our full multi-tester review which we did at the launched of the watch, and a long-term review from Nick, who used the Pace 4 for six months while training for the London Marathon and also tested the Aluminium model of the watch.
What’s New?
The main updates the Coros Pace 4 has on the Pace 3 are its AMOLED display, extra ‘Action’ button and a built-in mic. It still offers great battery life despite the new screen, and will actually outlast the MIP Pace 3 in GPS modes.
Compared with the Coros Pace Pro, which is a little more expensive, the Pace 4 is smaller, lighter and has the extra button and mic. The Pace Pro’s big advantage over the Pace 4 is its offline maps, and it also has a larger 1.3in display.
Coros continues to update the Pace 4 with handy new features, and actually added offline maps to the watch via a software update in September 2026.
The Run Test: Likes
The Coros Pace 4 is an extremely light and thin watch, which makes it very comfortable to wear 24/7. Compared to bulky sports watches like the Garmin Fenix 8 Pro you barely notice the Pace 4 while wearing it, and runners with skinny wrists will definitely appreciate its diminutive design.
We’re also fans of the bright AMOLED display, which is a lot clearer and more engaging in all conditions than the MIP screen Coros uses on other watches, including the Pace 3.
It has also proved an accurate watch during our testing, especially when it comes to GPS accuracy. We tested it against reliable trackers like the Garmin Forerunner 970, Suunto Vertical 2 and Apple Watch Ultra 3, and the Pace 4 always produced accurate GPS tracks during our runs and bike rides, including at city events like the London Marathon.
While the heart rate accuracy from the optical sensor wasn’t infallible, it was very good during testing as well. We compared it with the readings from a chest strap monitor on each run and the Pace 4 was usually within a few beats and when it did go wrong, it usually got back on track quickly.
You get a lot of features packed into this tiny watch as well, notably the same training analysis you get on all Coros watches, going up to the top-of-the-range Vertix 2S. Coros has a great record of adding features to its older watches too, and brought maps to the Pace 4 in September 2026.
Battery life is also a like with the Pace 4, because for a small watch with a bright display it surpasses expectations, especially in how long it can track while in dual-band GPS mode. It lasted us five days on a charge with the screen always-on, running every day, and 10 days with the screen set to raise-to-wake.
The Run Test: Dislikes
The Pace 4 lacks smart features, and you can’t customise the watch faces as much as on other watches. Coros does suggest that music controls are coming soon though, which would be a big update to their watches, which currently only offer storage for MP3 files.
We also found that it was easy to trigger the touchscreen and dial control on the Pace 4 accidentally, which was an annoyance when wearing gloves or a jacket in particular. This means you have to use the screen and button lock setting at times.
Verdict And Alternatives
The Coros Pace 4 has a good claim to be the best value running watch on the market, and it has some key advantages on the options from other brands at this price. It’s easier to use than the Suunto Run 2 and has better training analysis, and it offers multi-band GPS and a multipart mode as key upgrades on the Garmin Forerunner 70, though the Garmin has a better design and some more insightful training analysis features.
If you want more smart features on your watch the Garmin Forerunner 170 has NFC payments and can link up with streaming services. It’s a little pricier than the Coros Pace and doesn’t have as long battery life, but the Forerunner 170 is another excellent, affordable running watch to consider.
