BBC Sport - World's coldest marathon: Athletes compete at the North Pole

Tackling the world's coldest marathon

The world's hardest, and coldest, marathon has taken place at Russia's Barneo ice station at the geographic North Pole.

The 26.2-mile (42.2km) race, in temperatures as low as -30C (-22F), tempted 47 competitors from 20 countries to pit themselves against the elements.

American Mike Wardian was first home in four hours, seven minutes and 40 seconds. Germany's Anne-Marie Flammersfeld won the women's event in a time of 4:52.45.
