I completed my tour down the Great Allegheny Passage from Pittsburgh, PA, to Cumberland, MD, and down the C&O Canal Towpath from Cumberland to Georgetown, MD on 19 August 2014. This was one of the best bicycle touring experiences that I have had. The scenery is great and historic significance of the trail is interesting. Almost all of the 356.1 miles that I rode were off road on trails that were more than acceptable. Read all of the details here.
