swim the length of a pool will equal a SWOLF score of 40. Generally, the lower your SWOLF is for a certain distance and
style, the more efficient you are.
SWOLF is highly individual, and thus should not be compared to SWOLF scores other people have swam. It's rather a
personal tool that can help you improve and fine-tune your technique, and find an optimal efficiency for different
styles.

POOL LENGTH SETTING

It's important that you choose the correct pool length, as it affects pace, distance and stroke calculation, as well as
your SWOLF score. The default lengths are 25 meters, 50 meters and 25 yards, but you can also set it manually to a
custom length. The minimum length that can be chosen is 20 meters/yards.
The chosen pool length is shown in pre-training mode. To change the pool length, tap the quick menu icon
to
access the Pool length setting and set the correct length.

OPEN WATER SWIMMING

When using the Open water swimming profile, the watch records your swim distance, time and pace, stroke rate for
freestyle as well as your route.
Freestyle is the only style that the open water swimming profile recognizes.
Pace and Distance: Your watch uses GPS to calculate pace and distance during your swim.
Stroke rate for freestyle: Your watch records your average and maximum stroke rates (how many strokes you take
per minute) for your session.
Route: Your route is recorded with GPS, and you can view it on a map after your swim in the Flow app and web
service. GPS does not work underwater, and because of this your route is filtered from GPS data acquired when your
hand is out of the water or very close to the water surface. External factors such as water conditions and satellite
positions can affect the accuracy of the GPS data, and as a result data from the same route can vary from day to day.

MEASURING HEART RATE IN WATER

Your watch automatically measures your heart rate from your wrist with the new Polar Precision Prime sensor fusion
technology, offering an easy and comfortable way to measure your heart rate while swimming. Although water may
prevent the wrist-based heart rate measurement from working optimally, the accuracy of Polar Precision Prime is
sufficient to allow you monitor your average heart rate and heart rate zones during your swimming sessions, get
accurate calorie burn readings, your Training Load from the session and the Training Benefit feedback based on your
heart rate zones.
To ensure the best possible accuracy of your heart rate data, it's important to wear the watch snugly on your wrist
(even more snugly than in other sports). See
Training with wrist based heart rate
for instructions on wearing your
watch during training.
