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 (
Customizing the Data Screens, page 81
