The new Coros Pace 4 has significantly updated hardware and new software features, including a display-based flashlight and a new microphone.
The Coros Pace 4 is a sleek, ultra-light GPS watch built for runners and triathletes who prioritize performance and precision and also want a lot of value in a moderately priced watch. It hits a sweet spot: it brings “big watch” performance features (dual-band GPS, serious sensors, training tools) into a “small watch” form (lightweight, thin, wearable 24/7), and it does so at a very competitive price. If you want serious training support without the bulk or cost of the ultra-premium models, the Pace 4 is a sleek and sophisticated fitness device at a relative bargain of a price.
Featuring a vibrant 1.2-inch AMOLED display housed in a slim 11.8 mm body that weighs just 32g with the nylon strap, it combines comfort with cutting-edge capability. The watch offers dual-frequency GNSS for superior location accuracy, an upgraded heart-rate sensor, and impressive endurance—up to 19 days of daily wear or 41 hours in GPS mode. With a balance of simplicity, comfort, and reliability, the Pace 4 stands out as one of the best-value training watches for athletes who prefer function over flashy smartwatch extras.
In daily use, that comfort makes a noticeable difference. Whether you’re running, resting, or sleeping, the Pace 4 feels barely there—a major advantage over bulkier alternatives. The polymer case lacks the premium feel of metal-bodied watches, but given the weight and price point, it seems like an entirely reasonable compromise.

When it comes to performance, the Pace 4 focuses on the essentials that athletes care about most: accurate GPS, robust training metrics, dependable heart-rate tracking, and long battery life. Coros advertises up to 41 hours for GPS recording and 19 days for everyday use, and our early wear-testing suggests those figures hold up well—impressive for a watch with an AMOLED screen.
The addition of dual-frequency GNSS receiver enhances satellite accuracy, delivering faster and more reliable location data in dense urban areas or under tree cover. Meanwhile, the improved optical heart-rate sensor, featuring larger LEDs and a snugger fit, minimizes fluctuations during high-intensity efforts.
On the software side, the Coros Pace 4 allows access to advanced tools like Running Fitness, Race Predictor, Virtual Pacer, and personalized training plans, along with detailed HRV, sleep, and recovery tracking. A clever new touch is the built-in microphone and “Voice Pins” that allow you to drop quick audio notes during workouts that sync automatically to the Coros app.
Priced at $249, the Coros Pace 4 delivers outstanding value for serious runners. It rivals more expensive models in performance, making it one of the strongest mid-range GPS watches available.
However, there are a few compromises. It supports breadcrumb navigation, but it lacks full offline maps. Smartwatch functions are basic, with limited app integration, and its 4 GB storage might feel tight for heavy mapping or music use.
For runners and triathletes seeking a lightweight, training-focused, and budget-friendly watch, the Coros Pace 4 is an excellent choice. It combines minimalist design, dependable accuracy, and powerful fitness tools at a highly competitive price.
