Coros Pace 4 Long-Term Review: Still the Best Value Running Watch

Introduction

The Coros Pace 4 sits at the entry level of Coros’s range, and after six months of continuous testing, including a full London Marathon training block, it remains one of our favorite running watches. It is lightweight, accurate, and consistently gets new features through software updates. For many runners, it is arguably the best value running watch available right now.

This long-term look covers what has held up well, what has not, and how it compares to the alternatives at and around its price point.

Design and Comfort

The Pace 4 is a small, thin watch at just 11.8 mm thick, with a mostly plastic construction that keeps it comfortable to wear around the clock. The watch itself weighs under 30 g, roughly 32 to 33 g on a nylon band and about 40 g on silicone. Even the aluminum “Black Crystal” version, which adds an aluminum bezel, stays around the same weight because the rest of the body is still plastic.

You get a 1.2-inch AMOLED touchscreen with a glass cover, a digital dial on the top right for navigating menus, and Coros’s action button for switching between screens like breadcrumb navigation and music controls during an activity. The screen is clear and bright enough indoors and out, and even the always-on mode is legible at a glance.

Durability has been genuinely good for a plastic watch: no marks or scratches on the body or glass screen over six months. The aluminum model adds a slightly more premium feel, closer in spirit to watches like the Garmin Forerunner 570, though it still does not feel as upscale as more expensive metal designs.

GPS and Heart Rate Accuracy

Accuracy is where the Pace 4 quietly shines. Over roughly 1,500 miles of running, including the Paris Half and the London Marathon, GPS tracks have been near flawless, closely matching a Garmin Forerunner 970. The watch uses a dual-band GPS chipset, and the minor drift that appeared around Canary Wharf during the marathon is the kind of thing you expect in a crowded race.

Pacing and distance on road loops and park workouts have been spot-on, making it easy to trust for structured training. Instant pace is generally considered less responsive than some other brands, but using lap pace or rolling pace gives more stable averages, and even current pace stayed reasonable in testing.

Heart rate tracking from the optical sensor has been solid. Readings occasionally start slightly off at the beginning of a run or right after a pause, but they self-correct and have never been wrong for an entire run. Race heart rate data from the half marathon and marathon matched the Forerunner 970 very closely.

Battery Life

Battery life is a real strength for such a small watch. Coros claims up to 19 days in watch mode, dropping to about 6 days with the always-on display, plus 24 hours of GPS tracking with the screen always-on (31 hours with raise-to-wake).

In practice, about 5 days per charge with the always-on screen, sleep tracking, and daily runs is realistic, stretching beyond a week on raise-to-wake. Charging is handled through a USB-C adapter that connects to the proprietary pins on the back, so any USB-C cable works.

Useful Features Added Over Time

One of the best things about the Pace 4 is that Coros keeps improving it after launch. Software updates have brought a weekly mileage widget, music controls, hill alerts that show how much climbing or descending remains, and a pacing strategy feature for judging effort split-by-split in races, which is especially handy for hilly marathons.

The training analysis deserves mention too. Race predictions and threshold pace estimates have been very accurate in testing, and the presentation hits a nice balance: useful pointers and clear fitness trends without drowning you in data. Overnight HRV status adds a simple recovery signal on the watch.

The watch is also snappy throughout. GPS lock, menu scrolling, and saving runs are all quick, and it feels noticeably more responsive than some more expensive watches during testing.

Things to Consider Before Buying

The Pace 4 is not trying to be a smartwatch. Music storage is limited to MP3 files with no streaming service support, though phone music controls are now included. Watch face customization is limited, which is worth knowing if you like to tinker.

There are no onboard maps. Breadcrumb navigation covers most situations, but the more expensive Pace Pro adds maps and a slightly larger screen. Durability is also not at the level of sapphire-and-metal designs, so rugged outdoor users should look elsewhere. Two smaller annoyances: buttons may feel slightly less crisp over time, and the digital dial sits close enough to the wrist that it can be triggered accidentally, though button lock solves this.

How It Compares

Against the Garmin Forerunner 165, the Pace 4 is the better running watch at a slightly lower price, and it undercuts the Forerunner 265 by a fair margin unless the latter is deeply discounted. Garmin generally offers a slicker interface and stronger smart features, but it tends to reserve running features for pricier watches, while Coros is more generous at this level, offline maps aside.

The Suunto Run is another good lightweight option, but the Pace 4 edges it on accuracy and overall running experience. Amazfit’s affordable watches often look more premium with more metal, but the run experience is not quite as clean. If you want a true smartwatch and use an iPhone, an Apple Watch SE or Apple Watch 11 in a good deal makes more sense, with a more polished everyday experience but weaker run-focused accuracy.

Within Coros’s own range, the Pace Pro adds maps and a larger screen for not much more money, the Pace 3 is cheaper with a similar feature set but no AMOLED screen, and the Coros Nomad offers a more rugged build, better battery life, and maps for outdoors-focused users.

Buying Advice

Buy the Coros Pace 4 if you want maximum running value: excellent GPS accuracy, dependable heart rate tracking, strong battery life, useful training analysis, and a watch that keeps getting better through updates. Look elsewhere if you need offline maps, deep smart features, or a rugged metal design, because you will usually pay more for those things elsewhere.

Conclusion

After six months of marathon training, city races, and everyday wear, the Coros Pace 4 has only grown on us. It nails the fundamentals runners actually care about at a price that undercuts most of the competition, and it stands as the best value running watch on the market right now.
