Coros Apex 42mm Multisport Watch


      To prevent injury, there’s nothing more crucial than training correctly. This watch is able to accurately determine your overall effort, broken down into stamina level (0-100) and training effect (0-6). Exerted way too much stamina? COROS Trainer will notify you it’s time to rest up. Based on the effort level and training history, you will then be able to see an advised recovery window before you begin your next activity.

      Equipped with track and navigation features, APEX can be your best tool when you need directions the most. Routes are uploaded and displayed on grid as a bread crumb trail with real time information on heading and elevation and alerts to help you get back on course.

      The Apex will learn your stride length through and intelligent algorithm. This unique algorithm embodies machine learning at its core to record your personal range of motion while running. This will build your very own stride model that will be used for indoor running or areas of weak GPS signal (such as tunnels).

      Through another algorithm with lactate threshold, VO2 Max and HR, the COROS Trainer dials-in your running training every day. Using your personal historical data along with metrics from your latest activity, such as pace, distance and HR - COROS Trainer will calculate a perceived effort and recommend a time for full recovery.

      Post workout, the fun begins. The COROS App will give you a complete graphical analysis of your training – including: VO2 max, recovery advisor, threshold pace, last-7 days training load, personal fitness index and plenty more. Additionally, you can connect to your favourite 3rd party applications such as STRAVA and TrainingPeaks and automatically upload your workouts.

      With all the data the COROS Apex can provide, you will be equipped with a great running partner that will help you become a smarter and more efficient runner.
