Hi Andrea. Wow, round trip! Good on you. I would do Harpers Ferry, Hancock, Cumberland, Ohiopyle, Pittsburgh. If you can stretch the trip one more day, you could do the reverse in 5 days also. If you can get it in time for the trip, I highly recommend purchasing the GAP Trail Book. Tons of detail, restaurant listings in town, suggested itineraries, camp site listings, and most importantly, an indestructible water proof map. Bring ear plugs for the camping near railroads (some come through every couple hours), make sure you have lights for your bike if you get caught out on the trail after dark (the C&O is very dark especially plus you'll need it for some of the tunnels), and bring a lock for your bike when eating in town (just to be safe).
