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).
I am interested in attempting the GAP from Cumberland to Pittsburgh. Is anyone aware of a supported or unsupported FKT for this route in either direction?
