Photo taken on April 25 shows participants compete during the second annual office chair championships in Bad Koenig, 30 kilometres southeast of Darmstadt, Germany. About 80 participants competed on a downhill stretch of road using especially adapted desk furniture. The downhill course measured 200 metres and included an additional challenge in the form of a small ramp. Additional propulsion methods such as rockets or motors were banned, so competitors fine-tuned their racing vehicles with in-line skating wheels and adopted a variety of positions, sitting upright or streamlining their bodies in a lying position, organiser Rene Karg said.(Source: Xinhua/AFP) Photo Gallery>>>
