Long course at Barton Forest. I fumbled two of the three major route choices, which probably cost me several minutes in the end.
From #7 to #8, I was planning to more or less follow the line through the valley and contour into the control. Instead, I misread my compass, got confused in the terraces northeast of #10, and veered southeast. By the time I saw the steep hill just before the road, I was in no-man's-land. I was forced to take a 700 meter rough compass towards a small depression with hardly any attackpoint to speak of. Fortunately, I saw the campground road in time, which helped me regain my bearings near the control. Estimated time lost: ~2 minutes.
From #9 to #10, I never saw the southern route choice option along the road. Instead, I ran straight through the forest, losing about a minute. It didn't help that I misread the thickets around the control, losing another 30 seconds.
