The Baikal Ice Marathon is one of the world’s toughest endurance challenges. Over the years, the one-of-a-kind event has seen participants from over 50 countries. These are athletes with a heart of steel – they race across a 42 kilometer course across the completely frozen surface of Baikal, the oldest and deepest freshwater lake on Earth. Every year, the Baikal Ice Marathon is held for a noble cause – the Preservation of Clean Water. This year its 10th edition took place on March 1.
Although the terrain for the marathon is predominantly flat, it is still considered to be one of the world’s 10 most challenging competitions because of the freezing Siberian weather. The cold northern winds and harsh, unpredictable climate is, in fact, the biggest challenge faced by runners. In past marathons conditions have varied in severity – from high winds and biting cold, to a sunny sky with almost no chills. The lake’s surface is another problem; at times it can be hard and uneven, covered in small hills of ice rubble. Geometric springs and seismic activity beneath the ice may weaken it to form holes.
