The most difficult adventure-expedition outdoor competition organized in the Czech Republic. Four-member teams can expect a track over 400 km long that has to be done non-stop. Competition strategy (speed, relaxation, sleep, food…) is up to the teams themselves. The course is marked on a map by check points. Each team tries to find their optimal way between the check points.
During the competition the participants must prove their psychical and physical preparedness, individual skills as well as their ability of team cooperation. Even if only one member cannot overcome the difficulties of the competition and quits, the effort of the whole team is over.
The race is international championships of the Czech republic and is a part of the European cup AREuroSeries.
