acceleration sensor readings for measuring your running speed

FusedSpeed benefits you the most when you need highly reactive
speed readings during training, for example, when running on
uneven terrain or during interval training. If you temporarily lose
the GPS signal, for example, Suunto Ambit3 Peak is able to continue
showing accurate speed readings with the help of the GPS
calibrated accelerometer.
