World's Elite Triathletes Battle It Out At Hawaii's Grueling Ironman World Championships

There are over twenty Ironman competitions held around the world. However none compares to the original one that takes place in Kona on Hawaii's Big Island during the second weekend of October. Now in its 36th-year, this grueling event that is dubbed the "World Championships", is considered the most prestigious Ironman race. That's because while the Hawaiian event is no different from any other Ironman challenge in terms of distance, the natural environment makes it the toughest of them all.
