Depends on how fast you want to go.
If you want to race, or you want to do a long charity ride that has a cutoff time, or you want to ride with a specific group that averages a certain speed, then use that to set a goal.
Otherwise, do what makes you happy.
Of course, there's no point in racing, or doing a long charity ride, or riding with a specific group, unless doing that makes you happy...
