Ironman Triathlon. An Ironman Triathlon is one of a series of long-distance triathlon races organized by the World Triathlon Corporation (WTC) consisting of a 2.4-mile (3.86 km) swim, a 112-mile (180.25 km) bicycle ride and a marathon 26.2-mile (42.2 km) run, raced in that order and without a break.
The average bike time for an Ironman also depends on your age and gender. Women post slower bike splits than men of equal caliber, and older athletes, on average, tend to be slower as well. This is true for elite riders and age-group athletes.
