Coros Pace 4 specifications and in-depth review

Coros Pace 4

Manufacturer: Coros

The Coros Pace 4 is a lightweight sports watch built for athletes who want detailed performance tracking in a compact form. Weighing just 40 g and measuring 11.8 mm thick, it carries a 1.2″ OLED screen with a resolution of 390 x 390 px and a pixel density of 459 ppi, keeping the display sharp and readable during activity. Always-On Display mode is supported, and the touchscreen interface is protected by branded damage-resistant glass, with a replaceable 22 mm band for customization.

On the performance side, the Coros Pace 4 integrates GPS with fast lock capability, Galileo support, a heart rate monitor, pulse oximeter, barometer, compass, gyroscope, accelerometer, and a body temperature sensor. Battery life reaches 19 days in standard mode and 41 hours with GPS active, charging fully in around 2 hours. The watch supports multi-sport mode, swim stroke counting, sleep tracking with reports, HRV tracking, VO2 max measurement, and readiness scoring. Connectivity includes Wi-Fi 4 (802.11n), Bluetooth, iOS and Android compatibility, and 4 GB of internal storage, while the companion app offers coaching, route support, calendar sync, and music playback at no cost.

Pros
  • Battery lasts up to 19 days in standard use and 41 hours with GPS active, making it well-suited for extended training and travel without frequent charging
  • The OLED display runs at 459 ppi with Always-On mode supported, offering sharp visibility during outdoor activities
  • At 40 g and 11.8 mm thick, the watch is notably compact and lightweight for everyday and athletic wear
  • Sensor suite covers GPS with fast lock and Galileo support, heart rate, blood oxygen, barometer, compass, gyroscope, and body temperature, providing thorough physiological and environmental data
  • Multi-sport mode, automatic activity detection, swim stroke counting, trackback mode, and sleep tracking with reports make it versatile across a wide range of activities
  • The companion app is free and ad-free, supporting coaching, calendar sync, music playback, goal setting, routes, and data export at no ongoing cost
Cons
  • No NFC support, which rules out contactless payments directly from the watch
  • Wireless charging is not available, requiring a physical cable connection every time
  • Does not support ANT+, limiting compatibility with certain third-party fitness accessories
  • Fast and slow heart rate notifications and irregular heart rate warnings are absent, reducing passive cardiac monitoring
  • No map upload capability, which may limit navigation use in unfamiliar terrain
  • The app does not support personalisation and requires an account to use, reducing flexibility for some users
Who is this for?

This watch suits dedicated runners, triathletes, and outdoor enthusiasts who need reliable, multi-discipline tracking in a lightweight package. Its extensive sensor suite — covering GPS with Galileo, heart rate, blood oxygen, barometer, and body temperature — makes it well-matched for athletes who monitor physiological data closely across varied environments and conditions. The 19-day battery life combined with 41 hours of GPS endurance appeals to users who train frequently and need a device that keeps pace without constant recharging. Those who also want to track recovery through HRV, VO2 max, and readiness scores will find the health monitoring features genuinely practical for structured training routines.

Who is this NOT for?

Users who want contactless payment or NFC-based features will find this watch lacking, as it carries no NFC support. Those who rely on ANT+ accessories such as certain cycling sensors or external cadence meters will also face compatibility limitations. It is not suited to users who want turn-by-turn navigation via uploaded maps, since that functionality is absent. Additionally, anyone looking for passive cardiac safety alerts — such as irregular heart rate warnings or fast/slow heart rate notifications — will not find those features here, making it a less suitable choice for users with specific health monitoring requirements beyond general fitness tracking.
