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 watch 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 Garmin Connect account. You can also select stroke type as a custom data
field (
Customizing the Data Screens, page 85

Auto Rest and Manual Rest
NOTE: Swim data is not recorded during a rest. To view other data screens, you can press UP or DOWN.
The auto rest feature is available only for pool swimming. Your watch automatically detects when you are
resting, and the rest screen appears. If you rest for more than 15 seconds, the watch automatically creates a
rest interval. When you resume swimming, the watch automatically starts a new swim interval. You can turn on
the auto rest feature in the activity options (
).
TIP: For best results using the auto rest feature, minimize your arm motions while resting.
During a pool or open water swim activity, you can manually mark a rest interval by pressing BACK.
Training with the Drill Log
The drill log feature is available only for pool swimming. You can use the drill log feature to manually record kick
sets, one-arm swimming, or any type of swimming that is not one of the four major strokes.
1 During your pool swim activity, press UP or DOWN to view the drill log screen.
2 Press BACK to start the drill timer.
3 After you complete a drill interval, press BACK.
The drill timer stops, but the activity timer continues to record the entire swim session.
4 Select a distance for the completed drill.
Distance increments are based on the pool size selected for the activity profile.
5 Select an option:
• To start another drill interval, press BACK.
• To start a swim interval, press UP or DOWN to return to the swim training screens.
