Morgan & Stoyan (did not give their full name) posted the route on our old website:
"Myself and another runner did a pretty spirited loop (self-supported) and were wondering if we were the first to record a time. If not, if we did anything of note. Here is our effort:
John Muir Blue Loop (counterclockwise)
July 5, 2014
Support came in the form of having another runner with me. Otherwise, water and food carried in/out.
The route is within the John Muir trail system of the Southern Unit of Kettle Moraine State Forest.

Note that previously we had an incorrect GPX track on our route map, which skipped a ~1.5-2.0 mile loop (the Gnome Loop) at the northern end of the route.
