The Allegheny 100: A True Hiking Challenge

How am I just finding out about this now?  In researching an unrelated blog topic I came across the Allegheny 100 Hiking Challenge.

The A-100 as it's called by those in the know, of which I am now one, challenges hikers to trek either 25, 50, 75 or 100 miles on a stretch of the North Country Scenic Trail in Pennsylvania's Allegheny National Forest. It's all done over a 50-hour span.
