I drove a couple of miles to Saylorvile so I could test out those campground trails that I found a month or 2 ago. I spent about 4 enjoyable miles on them, though with repeating sections, there was maybe 3 miles worth. It was mostly prairie with a little singletrack, so a little better than the closer prairie section.
I returned to the car before 7miles, and I figured I could run to a steeper hill and still get 8. After 6 hill sprints, I underestimated and it didn't take much to finish off 9.
I did a lot more hills than expected today with a good variety of slower and faster miles.
