The Ironman: 2.4 mile swim, 112 mile bike, 26.2 mile run. Ever since John Collins and his buddies decided to combine the three toughest endurance races into one race in 1978 to see whether the swim, bike, or run was the toughest discipline, completing an Ironman has been considered the ultimate achievement of almost every triathlete. Despite the grueling nature of the race, this race is a popular as ever, with plenty of events to choose from.
