l Ascent and descent are less than 30 meters
When running on different surfaces (e.g. road, trail, treadmill), use a different sport profile for each of them to
achieve the best calibration for each surface.
To calibrate the stride sensor automatically, choose
l Settings > Sport profiles > Running> Stride sensor > Calibration > Automatic
Automatic calibration can also be started during a session, when the stride sensor is in use. Press and
hold LIGHT to enter the Quick menu and then choose Stride sensor > Calibration > Automatic.
RUNNING CADENCE AND STRIDE LENGTH
Cadence* is the number of times the foot with the stride sensor* hits the ground per minute. Stride length* is
the average length of one step. That is the distance between your right and left foot contacting the ground.
Running speed = 2 * stride length * cadence. There are two ways to run faster: moving your legs at a higher
cadence or taking longer steps. Elite long distance runners typically run with a high cadence of 85-95. On
uphills, typical cadence values are lower. On downhills they are higher. Runners adjust stride length to gather
speed: stride length increases as speed increases.Yet one of the most common mistakes novice runners
make is over-striding. The most efficient stride length is the natural one the one that feels most comfortable.
You will run faster in races by strengthening your leg muscles so they take you forward with a longer stride.
You should also work on maximizing cadence efficiency. Cadence does not progress easily, but if properly
trained, you will be able to sustain it throughout your runs and maximize your performance. To develop
cadence, the nerve-muscle connection needs to be trained - and reasonably frequently. A session of cadence
training a week is a good start. Incorporate some cadence work into the rest of your week. During long easy
runs, you could include some faster cadence every now and then. A good way of improving stride length is to
undertake specific strength work, like running hills, running in soft sand, or running up steps. A six-week
training period including strength work should result in noticeable improvements in stride length, and if
combined with some faster leg speed work (such as short strides at best 5km pace), noticeable
improvements should be seen in overall speed, as well.
POLAR SPEED SENSOR BLUETOOTH® SMART
PAIR A SPEED SENSOR WITH V800
Make sure the speed sensor has been correctly installed. For more information on installing the speed sensor
refer to the user manual of the speed sensor.
There are two ways to pair a speed sensor with your V800:
1. Press START in time view to enter pre-training mode.
2. V800 starts searching for your speed sensor. Rotate the wheel a few times to activate the sensor. The
flashing red light in the sensor indicates that the sensor is activated.
3. The device ID Pair Polar SPD xxxxxxxx is displayed. Choose Yes.
