After three years of planning and over 10 years of extreme unicycling, Lutz Eichholz succeeds in the unicycle descent of the 5671m high Damavand in Iran. Despite enormous problems with the high attitude, injuries in the team and weather fluctuations between 40° and -7° Celsius, Lutz Eichholz succeeded in the record breaking mountain descent. Never before has a unicyclist attempted to descend such a high mountain.
