The Great Allegheny Passage (aka the GAP) is a 150-mile rail trail that connects downtown Pittsburgh, Pennsylvania to the western end of the Chesapeake and Ohio (C&O) Canal in Cumberland, Maryland. From there travelers with the time and motivation can continue for another 184 miles to Washington, DC on the canal’s tow path adjacent to the Potomac River. Earlier this month my friend Jeff and I took Amtrak’s Capitol Limited train from DC to Pittsburgh with our bikes in a baggage compartment, and started the Passage ride to Cumberland the next morning. At its Pittsburgh end the rail trail begins in a downtown park, at the point where the Allegheny and Monongahela Rivers join to form the Ohio River (which, in turn, joins the Mississippi almost a thousand miles downstream). Along our ride to Cumberland we passed over the Eastern Continental Divide, which separates river basins that flow to the Gulf of Mexico from those that flow east into the Atlantic. We took four days, riding between 33 and 43 miles a day. This was a leisurely pace by serious biker standards. A pair of brothers we met were riding all 334 miles to DC in four days (and an enthusiast named Chris Shue rode from Pittsburgh to DC in just under 24 hours a couple of years ago!). Along the way we stayed in a B&B (West Newton, PA), a guest house (Ohiopyle, PA), and at Donges Drive-In and Motel (Myersdale, PA), which is a bit like a motel, but is really unclassifiable!
The Passage trail winds alongside rivers, with many crossings along the way over old iron and steel train bridges that have been converted to trail use. Freight trains still run frequently along these rivers, passing at street grade through the small towns along the Passage trail. There’s an elevation profile of the 150-mile trail on the internet that shows a constant moderate upward grade for the 127 miles from Pittsburgh to Frostburg, PA – and then what looks like a steep slope running down the last 23 miles to Cumberland. Jeff and I spent a lot of time before and during the trip debating whether we would notice the downhill grade to Cumberland, because the elevation profile uses a scale that’s highly exaggerated. We did have to pedal on that final downhill leg, but it was easy going – suddenly we could breeze along at 15 mph without much effort at all – fantastic!
