Key Benefits
COROS PACE 4 is built for runners who want to train smarter and move faster. Weighing just 32 grams with the nylon band, it feels light on the wrist while delivering powerful performance tracking throughout the day.
The 1.2 inch AMOLED touchscreen keeps every detail clear, whether in bright sunlight or low light. With up to 41 hours of GPS use and 19 days of daily battery life, it keeps up with demanding training without constant charging. Built-in tools like Running Fitness, Race Predictor, Virtual Pacer, and personalised marathon plans help guide progress and performance.
Beyond training, it tracks recovery, sleep, HRV, steps, and menstrual cycles to give a complete view of how the body responds. A built-in mic allows quick voice notes during or after workouts, helping capture insights in the moment. Designed to stay secure, light, and responsive, it supports every run from start to finish.

This was recommended to me by a friend and it’s absolutely brilliant. Fantastic battery life, has so many different sports on it. Very accurate. So light u don’t know u have it on! Would highly recommend.
Great watch, perfect for running and general use with plenty of data. Great price, gifts and delivery from Healf too!
This is packed with great features and got it at a discount from Healf. Offers more features and better value than other brands with a similar price point. If you are looking for your first or next multiband GPS watch to track your fitness etc. look no more
Amazing battery life and focused entirely on being a running watch rather than a 'do everything' smart watch.
Fantastic fitness watch. Ideal for runs, walks, cycles. Great supporting app with good stats.
