Using Cadence Alerts
NOTE: Cadence alerts are a feature
of the Forerunner 305 only and can
only be set in Biking mode.
If you own an optional Garmin
cadence sensor (GSC
10), you
can use cadence alerts. The
cadence alert noties you if your
cadence exceeds or drops below
a specic number of revolutions
of the crank arm per minute
(rpm).
Setting a cadence alert is similar
to setting a heart rate alert. The
maximum cadence value allowed
is 255. Be sure to change to
Biking mode when setting a
cadence alert.

Training with Cadence
Cadence is your rate of pedaling
or “spinning” measured by the
number of revolutions of the
crank arm per minute (rpm).
There are two sensors on the
GSC 10: one for cadence and
one for speed. Cadence data
from the GSC 10 is always
recorded. The speed data from
the GSC 10 is only recorded and
used for distance calculation
when the GPS signal is weak or
the GPS is turned off.
For information about speed
zones, see page 50.
