The format is like a score-O but with a topographic map and scale 1:35000.
The controls were little papers at trees or other prominent features. It was a team race, so everybody had to run with a partner without splitting up, the time limit was 3:10 hours. I ran with Sasha to defend our victory from last year. we had a few problems to find the little papers with the codewords and missed one control (just looked at the wrong tree...), but in the end we managed to defend our victory.
