Coros PACE 4 GPS Sport Watch with AMOLED Touchscreen Black Silicone Band

The Coros PACE 4 GPS Sport Watch in Black Silicone is the same ultralight, high-performance watch as the Black Nylon and White Silicone versions, fitted with a black silicone band for a sleek, all-black aesthetic that suits both training and everyday wear. Built for runners, triathletes, and multisport athletes who want serious training analytics without the weight penalty, the PACE 4 delivers professional-grade performance tools in a package that weighs just 32 grams with the nylon band. The silicone band offers a secure, flexible fit that's comfortable for long training sessions and easy to clean after workouts.

The 1.2-inch AMOLED colour touchscreen delivers 164% higher resolution than its predecessor, with vivid, sharp visuals readable in direct sunlight. Battery life is a genuine strength: up to 41 hours in GPS mode and 19 days of daily activity tracking, covering everything from sprint sessions to ultra-distance events without a mid-race charge. The PACE 4 introduces voice tools via a built-in microphone — record voice logs, training notes, and voice pins during workouts hands-free, capturing insights in the moment without stopping to type.

Training analytics are where the PACE 4 excels: Running Fitness score, Race Predictor, Virtual Pacer, and personalised marathon training plans give you actionable data to train smarter. Health tracking covers heart rate, HRV, sleep quality, steps, recovery, and menstrual cycle monitoring. The watch is compatible with the Coros app for detailed post-workout analysis and training plan management. Browse the full Coros range or our computers and GPS collection for related products.

Frequently Asked Questions

What is the difference between the Black Silicone, Black Nylon, and White Silicone versions?
The hardware, features, and battery life are identical across all PACE 4 variants. The difference is the band material and colour: the Black Nylon is the lightest option at 32 grams. The Black Silicone and White Silicone versions use silicone bands, which are slightly heavier but offer a different feel and are easier to wipe clean. Choose based on your preferred aesthetic and band feel.

How long does the battery last in GPS mode?
The Coros PACE 4 provides up to 41 hours of GPS usage, making it suitable for ultra-distance running events and long triathlon races without recharging. In daily activity tracking mode (no continuous GPS), battery life extends to up to 19 days.

What are the voice tools and how do they work?
The PACE 4 includes a built-in microphone that allows you to record voice logs, training notes, and voice pins during or after workouts. This is a hands-free way to capture insights, pacing notes, or post-workout reflections without stopping to type. Note: the microphone is for recording only — the watch does not support voice commands for control.

Is it suitable for cycling as well as running?
Yes — the PACE 4 supports cycling activity profiles and GPS tracking for bike rides. However, for dedicated on-bike use with turn-by-turn navigation, mapping, and power meter integration, a dedicated cycling computer such as a Garmin Edge is the more capable option. The PACE 4 is primarily optimised for running and multisport use.
