A good itinerary for three days that I've done many times is:
--DC to Harpers Ferry
--Harpers Ferry to Hancock
--Hancock to Cumberland
You'll average about 60 mi. per day. The last day with be the most rustic and remote.
Not sure if you're camping or hoteling, but there are free campsites close to each town listed once you leave DC and of course hotel/B&B accomodations within each town.
