Changes

The {{Garmin 910XT}} is an update to the [[Garmin 310XT]] with extra features, but it's more expensive. Probably the most useful feature for most runners is the calculation of [[Firstbeat| Training Effect]], and the altimeter. The 920XT 910XT has been replaced by the [[Garmin 920XT]] which offers a lot more features, but its release has also dropped the price of the 910XT.
