Recording an Obstacle Racing Activity

When you participate in an obstacle course race, you can use the Obstacle Racing activity to record your time on
each obstacle and your time running between obstacles.
1 From the watch face, press START.
2 Select Obstacle Racing.
3 Press START to start the activity timer.
4 Press LAP to manually mark the beginning and end of each obstacle.
NOTE: You can configure the Obstacle Tracking setting to save obstacle locations from your first loop of the
course. On repeat loops of the course, the watch uses the saved locations to switch between obstacle and
running intervals.
5 After you complete your activity, press STOP, and select Save.

Swimming

NOTE: The watch has wrist-based heart rate enabled for swim activities. The watch is also compatible with the
HRM-Pro series, HRM-Swim
are available, your watch uses the chest heart rate data.

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
