The footing is rocky, muddy (a few river crossings) and loose in places. The trail is not maintained (non-existent) in some areas. Is the trail as tough as advertised? Yes and No. It’s no run down a nature trail (but at times it is just that), you will get wet and muddy. You won’t get swept down stream in any whitewater. Some big hills but no supplemental oxygen is needed. All in all, a great run in a beautiful environment…with stupid spots.
