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.
Training to race an Ironman requires a lot of time on the bike. This isn't just because you have to cover 112 miles, but because you have to cover 112 miles and still feel fresh enough to complete a full marathon.
