There's no other race quite like it - 26 miles across the frozen surface of the oldest and deepest freshwater lake on earth. The annual Baikal Ice Marathon is one of the world's toughest endurance challenges, with participants from over 50 countries competing in freezing Siberian temperatures.
The event, now in its tenth year, forces runners to endure the biting northern winds and the harsh, plunging temperatures in remote Russia. The lake's surface is another danger. The course can be hard and uneven because of small hills of ice rubble - while geothermic springs and seismic activity beneath the ice may weaken it to form holes.
這絕對是世界上最「酷」又最艱難的馬拉松賽。第10屆貝加爾湖冰上馬拉松日前盛大舉行，今年的賽事吸引了超過50個國家的運動員前來參賽。他們都有著鋼鐵般堅定的心志，要在世界上最深的淡水湖－貝加爾湖，完全凍結的冰面上跑完42公里。貝加爾湖舉辦一年一度的冰上馬拉松，宣揚保護淨水的理念。
