SOBO's, don't underestimate Katahdin

All bravado aside, it is almost 10 miles r/t and over 4000' elev gain.

10 miles r/t is a good day hike. Throw in 4000'+ elev gain and it become a good, stiff hike.

For mere mortals, it is a challenge.

If you are in shape, it is a good challenge.

If you are not in shape (as many thru-hikers starting out seem to be for some reason), it is a difficult and not-so-fun challenge.

Most people can do it, obviously. If you are in shape, it is more fun.
