John Newman submitted the route:

This 130km (80 mile) loop of the Blue Mountains weaves together jaw-dropping sights and a lot of the best single track in the area. It's a knockout. The loop can be run in either direction, starting from any point. Some sections are brutal but the views are worth it.

The O&W Rail Trail is a 27-mile recreational trail located in the Rondout Valley, from Kingston to Ellenville, NY. The trail is divided into four sections between one and 14 miles long, connected by approximately 7 miles of road. It follows the course of the New York, Ontario and Western Railway which was decommissioned in 1957.
 

This route begins at the Freedom Rock in Adel and heads East. The route includes the entirety of the trail (minus the Jefferson out/back) and includes a diversion from the trail due to the 2020 construction between Redfield and Adel. The diversion does continue on a gravel road that runs parallel to the trail for the entire final 10 miles.
(Editor's Note: when the trail is re-opened, the Route should be adjusted to eliminate the road section).

Der Karwendel Höhenweg führt durch den südlichen Teil des Karwendelgebirges in Tirol. Einzigartig ist dabei der mehrfache Blickwechsel zwischen der Einsamkeit der Karwendel-Wildnis und dem geschäftigen Treiben im Inntal. Man startet den Weitwanderweg vom Seefelder Plateau durch Wald und über Almflächen ins Hochgebirge, wo man Gamsbeobachtungen beinahe garantieren kann.
