At the heart of PACE 4 is a vivid 1.2 inch AMOLED touchscreen with a tapered edge for excellent clarity in all light conditions. Dual Frequency, all-systems GPS combined with a redesigned heart rate sensor delivers reliable pacing, distance, and physiological data you can trust. Whether you are training locally or racing somewhere new, accuracy stays consistent.

Battery life is built for real training weeks, not daily charging. Expect up to 41 hours of GPS use or 19 days of daily use, depending on settings. Sync seamlessly with platforms like Strava, TrainingPeaks, and Wikiloc, and benefit from free software updates that keep improving your watch over time.

PACE 4 goes beyond basic tracking with advanced running tools such as VO₂ Max, Lactate Threshold, Race Predictor, Virtual Pacer, and personalised marathon plans. A built-in microphone lets you record voice notes mid-run, while the COROS app brings together training load, recovery, sleep, HRV, and menstrual cycle tracking in one clear hub.

The COROS PACE 4 combines dual-frequency satellite tracking with a redesigned optical heart rate sensor to capture precise movement and physiological data. By using multiple satellite systems simultaneously, it reduces signal errors caused by buildings, trees, or terrain, giving you consistent pace and distance tracking wherever you train.

All your data is processed through the COROS app, where training load, recovery time, sleep stages, HRV, and health metrics are analysed together. Over time, this builds a clear picture of your fitness, helping features like VO₂ Max trends, Race Predictor, and personalised training plans adapt to how your body responds.
