- Standard GPS: Standard GPS only takes
one GPS reading per second and typically works well for normal use when
under standard conditions.
- All Systems On Mode: All Systems On mode turns on
all satellite systems simultaneously, including GPS, GLONASS, Galileo,
Beidou, and QZSS. 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
COROS VERTIX 2s 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.

Running Fitness represents your current marathon
performance level.
·
View race time and pace estimates for 5k, 10k, half
marathon, and full marathon distances based on your past 6 weeks’ training.
Training Load
·
Training load represents the amount of exercise stress
your body is subjected to, and is a function of exercise time and intensity..
Track how different workouts on different days affect the amount of impact your
body is sustaining, so you can build a plan that allows your body recover from
hard training, and push through plateaus once you are ready.
Training Status
Understand
the impact that recent training has on your body. This measurement consists of
3 different metrics:
- Base Fitness (42-day rolling
average): Think of this as your long-term metric. It measures your ability
to take on hard sessions from your long-term training.
- Load Impact (7-day rolling
average): Think of this as your short-term metric. It measures the amount
of impact brought to your body from short-term training.
- Intensity Trend (7-day rolling
average): This is the relation between the past 7 days of TL (load impact)
compared to your Base Fitness.
Recovery
·
Get a quick glimpse of your readiness for training,
factoring in your fatigue from recent workouts.

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

- 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.
