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 swimming history
and in your Garmin Connect account. You can also select
stroke type as a custom data field

Tips for Swimming Activities

• Press LAP to record an interval during open water
swimming.
• Before starting a pool swimming activity, follow the on-
screen instructions to select your pool size or enter a
custom size.
The watch measures and records distance by
completed pool lengths. The pool size must be correct
to display accurate distance. The next time you start a
pool swimming activity, the watch uses this pool size.
You can hold MENU, select the activity settings, and
select Pool Size to change the size.
• For accurate results, swim the entire pool length, and
use one stroke type for the entire length. Pause the
activity timer when resting.
• Press LAP to record a rest during pool swimming
Rest and Manual Rest,
The watch automatically records swim intervals and
lengths for pool swimming.

• To help the watch count your lengths, use a strong
push off the wall and glide before your first stroke.
• When doing drills, you must either pause the activity
timer or use the drill logging feature
Drill Log, page 11).

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
page 23).
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 LAP.
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 LAP to start the drill timer.
3 After you complete a drill interval, press LAP.
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.

• To start a swim interval, press UP or DOWN to return
to the swim training screens.

Multisport

Triathletes, duathletes, and other multisport competitors
can take advantage of the multisport activities, such as
Triathlon or Swimrun. During a multisport activity, you can
transition between activities and continue to view your
total time. For example, you can switch from biking to
running and view your total time for biking and running
throughout the multisport activity.
You can customize a multisport activity, or you can use
the default triathlon activity set up for a standard triathlon.
