I spent a day and a half backpacking the trails in the One Horse Gap area in the Shawnee National Forest in southern Illinois. I ended up hiking about 28 miles, which puts me at just over 550 for the year. Yes, I'm goal-oriented sometimes.
I mostly followed the loop suggested by the River to River Trail Society, but also made a few extra loops. Some of the trails are not much used and overgrown, but that's balanced out by a large number of user trails that don't show on the map at all.
Conditions were near ideal: highs around 80, lows about 50. Not much bug pressure, though the ticks are out in force. The whole area is overrun with poison ivy, so everything I was wearing went straight into the laundry when I got home.
We've had just enough rain in the area lately to soften the trails up, but not so much as to turn them into mudpits (well, except in a few areas - the whole area gets heavy horse traffic). Sadly this meant that waterfalls and cascades were mostly dry too.
I camped next to One Horse Gap Lake - a very nice spot, but there's an access road which means there is far too much trash strewn around. At least the motorcyclists who showed up late Monday night opted to ride back out again rather than partying. Not that I have anything against people partying, but I like my sleep.
I put a few more photos at Imgur in the interest of not hammering the Beehaw servers too hard.
I dunno that I'm all that fast; I usually average about 2.5 miles an hour. But I can keep going at that pace all day long without breaks except for lunch and to make camp. I usually set things up so I can snack and reach my water without taking my pack off, and I get plenty of stops when I take photos so I don't feel the need for breaks. Plus it's way easier to keep up a consistent pace when you're hiking alone. I shudder to think how long it would have taken to get a Boy Scout troop over this whole route.
