This is an out & back (approx. 41km) to the top of Morro do Bradador starting at the Monte Crista water park in Garuva.  The route was submitted by James Lehm:

'The Queen of the Belgian rivers'. Deep in the Ardennes and Gaume, the most beautiful wild river in Belgium and northern France flows into countless wild twists: the Semois/Semoy. It originates on the plateau of the Arelerland (Pays d'Arlon) in the middle of the capital of the province of Luxembourg, Arlon. In the gently undulating Gaume, the Semois turns from a stream into a river and gently flows through green meadows, on the way to the hard Ardennes massif.

The Catskill High Peaks are 35 summits that meet the following criteria:

The highest is Slide Mtn, at 4180'.

The TransAm has been run for decades, and there were even races in the 1920s (the famous "Bunion Derby") and again in the early 1990s.  A web search will yield much history, here's a brief summary:  https://www.outsideonline.com/2129171/brief-history-run-across-america  The course is open, and of course evolves with development of the road system, but the end points are fixed:  City Hall in San Francisco and New York City Hall (note that the TransAm footraces were Los Angeles to New York).
