In December 2010, former Wales rugby international Richard Parks set off on a record-breaking challenge to conquer the highest summits on every continent. His epic 737 Challenge - 7 summits including the 3 geographical poles in 7 months - would be a feat never before attained by a human being. When an injury brought his rugby career to a premature end, he set his sights on completing an adventure that would raise a million pounds to help cancer sufferers and after 18 months of preparation his first goal would be to reach the South Pole by the last day of 2010. The clock to complete the challenge would then start to tick.
