This 7.4 mile run of 505 ft. elevation gain starts in Historic Ellicott City, MD and takes you on foot through the heart of Catonsville, aka "Music City, Maryland."  It transits a series of old rail line converted to hiking and biking trails into Ellicott City and through Catonsville.  

L’Alta Via inizia a Villa di Teolo presso la Trattoria Vecchio Tram; ai piedi della Provinciale per Teolo si gira a sinistra.
Superato lo scolo Degora e l’Azienda Agricola Maltese Baroni, si prosegue in direzione nord per il sentiero che dapprima costeggia alla base il rilievo e poi sale al Monte Arrigon.

I hope this route gets some attention as it is a great addition to the routes in the Whites. It’s a full 100k, a loop, hits 10 of the 4ks, and spends time in the 2 wilderness areas. Lots of variety in the trails with nothing too technical and a good bit of runnable terrain. There are many start/stop locations, places to cache gear for self supported, and either direction would be great. Would make a great multi day backpack too.  Water is abundant except for the stretch from the bottom of the Tripyramid north slide over to the descent of Passaconaway.
