We're 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.Navigation TrackEquipped 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.Smart Learning Stride LengthIntroducing COROS' very own, Intelligent Stride 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).
