Triathlon vs Ironman – The Difference
A triathlon is an event that consists of three sports or disciplines put together and completed after one another. They are separated by “transitions” which allow the athlete to remove their wetsuit, pick up their bike, and put on their running shoes.
Triathlon first originated in France in the 1920s where the goal was to find who is the fittest athlete between a cyclist, runner, and a swimmer.
Since then triathlons have been split into multiple event distances:
– Sprint Distance
– Olympic Distance
– Half Ironman Distance
– Ironman Distance
– Ultra Ironman Distance
Ironman triathlon technically is a by-product of triathlon which originated in the later stages of 1978. The first triathlon started with only 15 participants. Because of the difficulty of completing the distance, the first person to cross the finish line would be called an Ironman.
Since then, the name has now been trademarked by Ironman. They have also gone on the organize other distance events such as Ironman 70.3 under their brand.
Although Ironman is one of the biggest triathlon event organizers, but there are still other Iron distance events around the world, they just aren’t run by the Ironman corporation, yet they still cover the same distance.
