36 Customizing Your Device
Training Effect value increases, telling you
how the activity has improved your fitness.
Training Effect is determined by your user
profile information, heart rate, duration,
and intensity of your activity.
It is important to know that your training
effect numbers (1.0–5.0) may seem
abnormally high during your first few runs.
It takes several activities for the device to
learn your aerobic fitness.

Data Fields
You can customize data fields on up to
four training pages for each sport. The
data fields you customize are saved for
the active sport. Some data fields are not
available because they are specific to a
sport mode.
Data fields with the * symbol display
statute or metric units. Data fields with the
** symbol require an ANT+ sensor.
Data Field Description
Cadence ** For running, cadence
is measured in steps
per minute (spm). For
cycling, cadence is
measured in revolutions
of the crank arm per
minute (rpm).
