I have an Edge 705, but from what I can gather they haven't changed the way Virtual Partner works. Set up a course, if you use bikeroutetoaster (for one at least) it will give you the option of setting speeds on the flat & climbs- apart from giving you an idea of how long it'll take to ride, that data will feed through the virtual partner & give you target times. Make sure the VP is switched on in the options, select the course from the Training menu (not 'Where to'), and the VP data will be there on screen as you ride.
