Fat and shy, Ben Saunders was the last kid in his class picked for any sports team " Football,
tennis, cricket - anything with a round ball．I was useless," he says now with a laugh．But back
then he was the one always made fun of in school gym classes in Devonshire, England．
It was a mountain bike he received for his 15th birthday that changed him．At first he went
biking alone in a nearby forest．Then he began to ride the bike along with a runner friend．
Gradually, Saunders set his mind on building up his body, increasing his speed and strength．At
the age of 18, he ran his first marathon．
The following year, he met John Ridgway and was hired as an instructor at Ridgway's School
of Adventure in Scotland, where he learnt about Ridgway's cold - water exploits.Greatly interested,
Saunders read all he could about North Pole explorers and adventures, then decided that this would
be his future.
In 2001, after becoming a skillful skier, Saunders started his first long - distance expedition towards
the North Pole．It took unbelievable energy．He suffered frostbite (冻疮) ,ran into a polar bear
and pushed his body to the limit, pulling his supply -loaded sled (雪橇) up and over rocky ice.
Next October, Saunders, 27, heads south from the coast of Antarctica to the South Pole and back,
a 2900 - kilometer journey that has never been completed on skis．
