The COROS PACE 4 is an ultralight GPS sports watch designed for runners, cyclists and endurance athletes who want advanced training metrics without the bulk of a traditional smartwatch. Combining a vivid AMOLED touchscreen, highly accurate GPS, improved heart-rate tracking and long battery life, PACE 4 is built for both everyday training and race day.

At just 32 g with the nylon band and only 11.8 mm thick, PACE 4 is designed to remain comfortable during long training sessions and overnight wear. The 1.2-inch 2.5D AMOLED touchscreen delivers sharp, vibrant data with automatic brightness adjustment for easy visibility in different lighting conditions.

The redesigned optical heart-rate sensor improves data reliability by reducing sudden spikes and drops, while All-Systems and Dual-Frequency GPS provide fast and accurate positioning across city streets, open roads and challenging trail environments.
