Swim Terminology
Length: One trip down the pool.
Interval: One or more consecutive lengths. A new
interval starts after a rest.
Stroke: A stroke is counted every time your arm
wearing the device completes a full cycle.
Swolf: Your swolf score is the sum of the time for one
pool length and the number of strokes for that
length. For example, 30 seconds plus 15
strokes equals a swolf score of 45. For open water
swimming, swolf is calculated over 25 meters.
Swolf is a measurement of swimming efficiency and,
like golf, a lower score is better.
Critical swim speed (CSS): Your CSS is the theoretical
speed that you can maintain continuously without
exhaustion. You can use your CSS to guide your training
pace and monitor your improvement.
Stroke Types
Stroke type identification is available only for pool
swimming. Your stroke type is identified at the end of a
length. Stroke types appear in your swimming history and in
your Garmin Connect account. You can also select stroke
type as a custom data field
