My KATY Trail segment is the third trail segment of my ride, and the longest of the three. This rail-trail stretches 239.2 miles/385.0 kilometers from Machens, Missouri (essentially a former railroad junction to the north of the St. Louis metro area) to the center of Clinton Missouri, a small city a little more than 65 miles/104.6 kilometers from downtown Kansas City, Missouri. It runs along the abandoned Missouri-Kansas-Texas (KATY) railroad line, hence the name.
