No. 5: North Pole Marathon.

By competing in the world’s coolest marathon, the North Pole Marathon, you will become one of a truly select few to race at the top of the world – at the Geographic North Pole. And you will feel on top of the world when you manage to overcome the extreme sub-zero temperatures to finish 26.2 miles in one of the remotest parts of the planet. But first you must ask yourself if you have got the nerve and drive to travel to the North Pole and run on Arctic ice floes, with 6 to 12 feet separating you from 12,000 feet of Arctic Ocean? Can you handle the extreme cold? Are you fit enough? Do you want to push yourself to the edge?
