BAIKAL ICE MARATHON, SIBERIA
At the Baikal Ice Marathon, runners race from one bank to the other across the frozen waters of the world’s largest and deepest freshwater lake. The surface is hard and uneven and although the ice is mostly covered by soft snow, areas of exposed, polished ice create conditions similar to an ice rink. In the depths of Siberia, participants must cope with freezing temperatures and strong, chilling winds. The featureless white landscape offers little sense of perspective and is only broken by flags marking the route, making this marathon as much of a psychological challenge as a physical one.
