TIP: To get the most accurate readings with FusedSpeed, only glance shortly at the
watch when needed. Holding the watch in front of you without moving it reduces the
accuracy.
FusedSpeed is automatically enabled for running and other similar types of activities, such as
orienteering,
floor ball and football (soccer).
3.18. FusedTrack
To save battery when exercising, some of the battery modes in Suunto 9 change the interval
of the GPS readings. To avoid getting bad GPS tracking when exercising Suunto 9 uses
FusedTrack. FusedTrack uses motion sensors to log your movement between the dierent
GPS readings, which will provide better tracking of your exercise.
FusedTrack is activated automatically during running and trail running when Ultra or
Endurance battery mode is chosen and it improves the tracking and distance accuracy
between the GPS readings. Endurance mode uses a GPS reading interval of 1 minute and
Ultra mode a GPS reading interval of 2 minutes.

It is important to train with intensity in mind and understand how that intensity should feel.
And don't forget, regardless of your planned training, that you should always take time to
warm up before an exercise.
