The Polar Race is one of the most extreme races in the world. One of the people I went to see at (of all things) Donald Trump's real estate seminar, managed to finish it this year.
2,000 people have climbed Everest.
400 people have been to Outer Space.
160 people have rowed the Atlantic Ocean in a row boat.
But, fewer than 100 people have ever reached a Pole on their own efforts (no dogs, no snowmobiles, no airplanes, etc.).
