1. get to hight and could not interpreted the stones. Find my 2nd control and go back to 1st from there.
2 - 4. Stupid up and downhill but easy to find. 6. Get to hight and have to go back from the stone. Vegetation was difficult to read there.
7 - 8 Approx. 200 m downhill with green areas and fallen trees not on the map. Ruined my knees there. At 8th control were many not mapped stones that was bigger than the one with the control. Missed the stone in the green by some meters and had to come from the track below. Control feels a little like bingo.
10. Was to hight and need ages to fix were I was.
