The route starts at Rainy Pass off of highway 20. This is the same trailhead as the popular Maple Pass Loop, which you will follow CCW until making a right at Heather Pass towards Black Peak. The trail goes over some boulder fields on the way to two lakes, Lewis Lake and Wing Lake. Wing Lake is at the base of Black Peak and has a clear view of the rocky mountain. Wing Lake is also where most mountaineers camp before a summit push. There are multiple routes up the mountain but the easiest and safest is through the South ridge.

This route follows a long trail section of the North Country Trail that runs through two state parks: Moraine State Park and McConnell's Mill State Park.  The area is historically known for its glacial activity as well as more recent strip mining, oil drilling, and formation of Lake Arthur.  The entire trail follows the blue blazes of the NCT.

The Western Maryland Rail Trail is a paved route that runs parallel to the C&O Canal in Western Maryland. The route begins in Big Pool, MD - in 2019, it was extended from 22 miles to 28 miles, ending in Little Orleans, MD.

Between Mile Markers 24 and 27, the Indigo Tunnel is permanently by-passed by using ramps to the C&O Canal Towpath. The by-pass is two miles long due to a bend in the Potomac River. The surface of the towpath is for the most part an even hard-packed dirt trail.

Likely the most popular running route in all of Japan.  Some races have been held, and likely there have been some very fast times.  Note that runners must go counter-clockwise.
