Got cocky from the very start, and veered off the trail into the woods to look for 1, but got entirely lost and without references. Eventually, lost valuable minutes by looking for the trail where I came from, the clearing, the square-shaped depression, the stone wall, and finally control 1.
Eventually my brain got accustomed to the environment, and decided to be very conservative, and stop and consult the map much more often than I would normally. On route from 5 to 6 was tricky, for lack of very visible features, and had to "read" the terrain like I never have before. Was hinted on the location of the control by seeing a couple of runners running away from a location, went there, and found the control.
On to 7, decided to use the long stone wall as a wide crash barrier, and eventually get me closer to the control.
Right after 8, descended a very steep slope between two cliffs. Later saw on the map exactly two cliffs, very close to each other.
12 was a bit tricky, but fun. Could appreciate the detailing of the map in describing the small depressions and hilltops.
