1 What is the Ironman triathlon?It is one of the toughest single-day endurance sports events in the world.It consists of a 3.8 km swim, 180.2 km bicycle ride, and a 42.2 km marathon run in that order, covering a total of 226.3 km.The race that I competed in has a 16-hour time limit.The mandatory cutoff time for the 3.8 km swim is 2 hours 20 minutes.The mandatory cutoff time for the athlete to complete the swim, transition, and biking is 10 hours.The mandatory cut-off for the run is 16 hours from when the athlete begins their swim.If you don't finish within these cut-offs, you will be assigned a DNF (did not finish).A DNF is probably the worst nightmare for Ironman triathletes.
