Previous generations of GPS watches only allowed for 2-3 systems to be turned on at once, we highly recommend that All Systems on is the GPS mode used for everyday workouts. 
• Dual Frequency Mode: is the most powerful and accurate satellite mode available. This powerful mode enables the Pace 3 to communicate with satellite systems in two simultaneous frequencies, bringing next-level accuracy even when you are in challenging conditions or environments.
• Ultra-Max GPS Mode: UltraMax GPS mode utilizes GPS, motion sensors and proprietary algorithms to extend the battery life without sacrificing too much of the tracking accuracy. For every 120 seconds, the GPS is switched on for 30 seconds. Ultra-Max mode will be the least accurate GPS tracking of all our GPS modes and is not recommended to be used unless necessary. 
• Battery Usage Report & Prediction
• Built into every COROS watch is a "Battery Usage" tool that allows you to view on-demand usage reports on the consumption of your watch battery during the current charging cycle. 
• To access the Battery Usage tool, hold the BACK/LAP button to access the Toolbox, then scroll until you find "Battery Usage"
• The Battery Usage tool will then display a graph that shows you the current battery percentage of your watch, a graph showing your historical battery drain, when your last charge was, and the estimation of how long your battery will last based on "standard use". 
• To view a more in-depth breakdown of the battery usage statistics, press the digital dial.
• From this screen you can see the following metrics: Remaining Power, Estimated Daily Use Left, Estimated Max Daily Use Left, Estimated GPS Use Left, Last Charge, Since Last Charge. You will also find the most common features which cause battery drain here, and what percent of your recent battery drain can be attributed to these common features. Below is an explanation of each of the common features which consume battery:
• System: Normal operating activities. Any type of regular maintenance on the watch or features that are vital to maintaining a functional watch (i.e. keeping the clock up-to-date) will fall within the "System" category
• Notifications: Any notifications which are pushed to your watch, both for workout alerts (lap alerts, etc.) and daily notifications (calls, text messages, etc). This is displayed as a number rather than being included in the overall percentage estimate.
• GPS Workouts: Any activity recorded which uses GPS signals to measure and record distance, etc.
• Backlight: Any power used to illuminate your watch screen. The more you use your backlight (Night Mode, Backlight Gesture, etc.), the higher this percentage is likely to be.
• Daily Heart Rate: Measurements taken that consume battery to provide daily heart rate data. You have the ability to specify this to "Real-Time" or "Every 10 Min"
• What sensors are in the watch? 
• 3D Compass, Accelerometer, All-Satellite Dual-Frequency GNSS, Barometric Altimeter, Electrocardiogram Sensor, Gyroscope, Thermometer, Wrist-based Heart Rate Sensor, Wrist-based Pulse Oximeter

Wearing Your Watch

To ensure that your watch can gather the most accurate data possible, here are a few best practice tips to follow. 

• Wear the watch tightly, but not so tight as to cut off circulation. It should fit snug and not slide around with movement. 
• Leave a 1cm gap between your wrist bone and the watch. The higher the watch is above the wrist bone, the more flush the surface of your skin, and the less likely the sensor is to be impacted by flexion in the wrist. 
• Keep your hands warm. The OHR signal comes from your blood reflection. So, the more blood flow you have, the better signal your watch will receive. The weather doesn’t need to be freezing to impact your OHR accuracy. As long as your hands feel cold, your blood flow is reduced significantly. The best way to solve this is to try and keep the area where your watch is located on your wrist warm.. Another suggestion is always warm up your body (and your hands) before starting your workout in the winter. 
• Wait for your watch to display a stable HR reading. Just like your body, your OHR sensor requires some warm-up too. It’s recommended to stay on the “Start” page and wait a little longer so the watch can filter some noise by itself. Our watches also provide an alert beep to let you know when it’s ready to go ( if sounds are turned off, you will see a heart symbol that will be solid and steady when ready) 
• Select the proper training mode. The regular running, cycling, and swimming algorithms are not specifically built for tracking rapid changes in heart rate. When you train with intervals, please select the Interval Training mode under Run mode for enhanced heart rate tracking sensitivity.

Advanced Running Metrics

Running Power (provided directly from all COROS watches)

• Power is the rate of effort used in running. Running uses more power than walking if the distance remains the same because the duration is shorter and speed increased. The power calculation is related to weight, speed, and other metrics. Running uphill with the same pace requires more power than running flat. Power data can help evaluate real-time workout intensity. Running power is a great tool to measure your training in addition to heart rate and other metrics.

Form Power

• The amount of power wasted due to inefficiencies in your running form. The lower this number, the better and more efficient the runner. This is similar to the previous Running Efficiency metrics (now removed) in terms of running form insights.
• Available only in the post-workout analysis when paired with COROS POD.

Ground Time

• Excellent: <210ms
• Better: 210-240ms
• Good: 240-270ms
• Average: 270-300ms
• Poor: >300ms
• Ground time measures the amount of time each of your feet are in contact with the ground. Advanced runners tend to have shorter ground time. Elite runners’ ground time can be as low as 180ms.

Left/Right Balance

• Orange: >L 51.5 Far more time on left foot
• Yellow: L 50.6-L 51.5 Slightly longer time on left foot
• Green: L 50.5—R 50.5 Good left/right foot balance
• Yellow: R 50.6-R 51.5 Slightly longer time on right foot
• Orange: >R 51.5 Far more time on right foot
• L/R balance measures the percentage of ground time spent on each foot. Track running and trail running may cause the reading to drift away from the desired green zone. If the reading exceeds 55, your risk of injury may increase. 

Stride Ratio

• Excellent: <6%
• Better: 6-8%
• Good: 8-10%
• Average: 10-12%
• Poor: >12%
• Stride ratio can help measure running efficiency. It is the ratio of stride height to stride length. When stride length is longer and stride height is lower, the amount of energy wasted going up and down is reduced and the running is considered more efficient. The stride ratio for advanced running form can be lower than 6%.

Stride Height

• Excellent: <5cm or <2in
• Better: 5-8cm or 2-3.2in
• Good: 8-12cm or 3.2-4.7in
• Average: 12-15cm or 4.7-5.9in
• Poor: >15cm or > 6in
• Stride height is the amount your body bounces vertically with each step. Lower stride height indicates that less energy is wasted bouncing up and down. Fatigue and incorrect running form may cause higher stride height.

Stride Length

• Stride length measures the distance from heel to heel when you take two steps. It is an important factor to evaluate running form and techniques. On average, an adult’s stride length is 65 cm / 2.13 ft during walking and between 90-150 cm / 2.95-4.92 ft when running. Many runners overstride believing this will increase the speed. However, this will increase the risk of injury on muscles and knees. It is critical to find the stride length that suits you the best for training and races with the help of advanced running metrics from the COROS POD.
