World champ triathlete breaks neck, comes back to finish Ironman

The Ironman triathlon is one of the most grueling competitions in the world. It could easily be seen as a form of self-torture. A true Ironman triathlon involves a 2.4-mile swim, a 112-mile bike ride and a 26.2-mile run. And in case you're not aware, the Ironman competition puts these three events back-to-back-to-back.
