1000 miles is cake. Jump on the interstate ride 500 miles turn around ride back.
Honestly if you want to eat up big miles everyday stopping and smelling the roses or sightseeing isn't going to happen unless you are extremely efficient at sight seeing. Even a 1k mile day takes a good chunk of your day and doesn't leave a lot of time to sightsee.
