Route: Great Allegheny Passage (GAP, MD/PA)

Maryland, US
Pennsylvania, US

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?
