Indoor Activities

The Forerunner device can be used for training indoors, such as

running on an indoor track or using a stationary bike. GPS is

turned off for indoor activities.

When running or walking with GPS turned off, speed, distance,

and cadence are calculated using the accelerometer in the

device. The accelerometer is self-calibrating. The accuracy of

the speed, distance, and cadence data improves after a few

outdoor runs or walks using GPS.

TIP: Holding the handrails of the treadmill reduces accuracy.

You can use an optional foot pod to record pace, distance, and

cadence.

When cycling with GPS turned off, speed and distance are not

available unless you have an optional sensor that sends speed

and distance data to the device (such as a speed or cadence

sensor).

Calibrating the Treadmill Distance

To record more accurate distances for your treadmill runs, you

can calibrate the treadmill distance after you run at least 1.5 km

(1 mi.) on a treadmill. If you use different treadmills, you can

manually calibrate the treadmill distance on each treadmill or

after each run.

Start a treadmill activity (Starting an Activity, page 2), and run

at least 1.5 km (1 mi.) on the treadmill.

After you complete your run, select STOP.

Select an option:

• To calibrate the treadmill distance the first time, select

Save.

The device prompts you to complete the treadmill

calibration.

• To manually calibrate the treadmill distance after the first-

time calibration, select Calibrate & Save > Yes.

Check the treadmill display for the distance traveled, and

enter the distance on your device.

Outdoor Activities

The Forerunner device comes preloaded with outdoor activities,

such as running and cycling. GPS is turned on for outdoor

activities. You can add new activities based on default activities,

such as walking or rowing. You can also add custom activities to

your device (Creating a Custom Activity, page 3).

Swimming

NOTE: The device cannot record wrist heart rate data while

swimming.

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. Swolf is a measurement of swimming efficiency and, like

golf, a lower score is better.

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 when you are viewing interval history. You can also

select stroke type as a custom data field (Customizing the Data

Screens, page 21).

Free Freestyle

Back Backstroke

Breast Breaststroke

Fly Butterfly

Mixed More than one stroke type in an interval

Drill Used with drill logging (Training with the Drill Log, page 4)

Tips for Swimming Activities

• Before starting a pool swimming activity, follow the on-screen

instructions to select your pool size or enter a custom size.

The next time you start a pool swimming activity, the device

uses this pool size. You can hold UP, select the activity

settings, and select Pool Size to change the size.

• Select BACK to record a rest during pool swimming.

The device automatically records swim intervals and lengths

for pool swimming.

Resting During Pool Swimming

The default rest screen displays two rest timers. It also displays

time and distance for the last completed interval.

NOTE: Swim data is not recorded during a rest.

During your swim activity, select BACK to start a rest.

The display reverses to white text on a black background,

and the rest screen appears.
