The Great Allegheny Passage (GAP) is a 150-mile trail from Cumberland, MD, to Pittsburgh, PA. The GAP is mainly well groomed crushed limestone that rides fast - most interest in this trail has been by cyclists.  However, on our old website a hiker claimed to have walked the GAP in 137h55m in June 2016 (self-supported).

The Shawangunk Ridge Trail begins at High Point State Park in New Jersey and runs 71 miles northward along the dramatic Shawangunk Ridge to Mohonk Preserve in New York. A trail description of the southern half of the The Shawangunk Ridge Trail can be found in The Long Path Guide. The northern half of the The Shawangunk Ridge Trail is shown on the Shawangunks map set.

The C&O Canal Towpath runs about 184.5 flat, unpaved miles from Cumberland, MD, to Washington DC. It is described on the Bike Washington website.  Most FKT interest has been by cyclists, which we don't currently track (that said, we are aware that Matt Kovacic rode 10h53m42s on 5/24/2020).

These routes are described on http://www.njpalisades.org/trails.html

NOTE:  It appears to be easy to go wrong on parts of this route.  Study it carefully before attempting an FKT!
