Plot Synopsis

Each year since 1978, Hawaii has hosted the IRONMAN WORLD CHAMPIONSHIP, a 140.6-mile challenge in which a field of international triathletes swim 2.4 miles, bike 112 miles and run 26.2 miles across rugged Hawaiian terrain. This competition has showcased not only the raw power and competitive nature of the top endurance athletes in the world, but also some of the most awe-inspiring stories of courage and determination from age-group athletes and everyday individuals competing alongside them. On March 23, 1980 ABC's WIDE WORLD OF SPORTS first telecast highlights from this event, when it was known as the ENDURANCE TRIATHLON WORLD CHAMPIONSHIP during its early years when the competition was still held on the island of Oahu. The IRONMAN website now streams the event live, and from 1991-20106 NBC broadcast a standalone special approximately 1-2 months after the race, covering the event while highlighting human-interest stories and presenting exclusive interviews with current and former World Champions and other IRONMAN finishers. Beginning in 2017, NBCSN provided three hours of live coverage of key parts of the event.
