I don't have a 2610 so, take this with a grain of salt. The info you seek should be in the track log. Connect your GPS to the computer, open Mapsource, click Transfer, then Receive From Device. Mapsource will download all the data from your GPS.
Then in the Track tab on the left you can highlight a track and look at it's properties or display it on the map. In there you will find more than you ever wanted. Speed, time, elevation, coordinates etc. It will have a list of points and each point will have all that data.
