Extreme Athlete Invents World Triathlon: In words and video, ESPN presents the story of Charlie Wittmack, an extreme sportsman who invented the World Triathlon -- swimming the English Channel; riding 9,000 miles from the spot to Calcutta, India; running 1,000 miles to Mount Everest; then climbing the mountain -- all so he could be the first person to do it. "This is the new marathon, the new Ironman. This is what people are going to strive to do," he said a year ago. "We're setting the groundwork for history." See if you think the price paid by his wife and young son is worth it.
