Is it possible to achieve with a purely plant-based diet (vegan raw food) outstanding performance in endurance sports? Is this not only unique, but possible with increase of performance for many years? Arnold Wiegand will be accompanied in his training and his diet in preparation for the World Championship in Triple Ultra Triathlon 2010 in Lensahn (D) and the ice swimming. In this competition 11 km swimming, 540 km cycling and 126 km running have to be done. The competition goes around the Clock. The recordings demonstrate which physical and mental skills are essential prerequisites for such a competition. Although this competition is organized for 19 years, only about 100 German crosses the finish line.
