The Pace series from Coros is a popular choice among runners, known for its light weight and durable battery. The latest Pace 4 generation maintains the familiar minimalist philosophy while upgrading its display, battery life, and training support capabilities.

The device weighs 32 grams with a nylon strap, making it one of the lightest GPS sports watches available. Its body is 11,8 mm thick, designed for comfortable wear during long runs or competitions.

The device features a 1,2-inch AMOLED touchscreen display, offering clear colors and good visibility in various lighting conditions. This marks a significant change from the previous generation, which used a memory-in-pixel (MIP) display.

According to the company, the Coros Pace 4 achieves a maximum battery life of 41 hours in GPS mode and 19 days of regular use. This represents an increase of approximately 16 GPS hours compared to the Pace 3. This battery level targets users with intense training regimens or those participating in long-distance races.

The watch supports new satellite modes, improving signal acquisition speed and GPS accuracy. The heart rate sensor has also been redesigned to reduce irregular fluctuations during activity tracking.

For the first time, the Pace series integrates a microphone, allowing users to log training or create Voice Pins during and after runs. This feature supports quick saving of information such as workout feelings, race strategies, or nutrition notes without manual input.

Regarding software, the device continues to offer advanced running training tools: running performance tests, effort pace, real-time training alerts, race performance prediction, and virtual pacer. Personalized marathon training plans are based on user data, combining heart rate variability (HRV) tracking, sleep, recovery time, and menstrual cycles.

The device also allows direct control of music and podcasts from the watch when connected to a phone.

Speaking about the new product, Lewis Wu, CEO of Coros, stated that the Pace 4 was developed based on user feedback from the Pace 3. The focus was on improving display, performance, and accuracy, while maintaining simplicity and wear comfort.

Coros currently focuses on developing endurance sports devices, combining lightweight hardware, long battery life, and a training data ecosystem. These devices target both amateur athletes and serious trainees.
