How long is a Full Ironman triathlon?

An Ironman is the longest triathlon distance out of the 5 recognised race lengths for the multidisciplinary event. If you are after a true challenge of your physical and mental fitness and endurance, an Ironman is often seen as the ultimate test by athletes and enthusiasts alike!

If you are looking to take part in a triathlon of any length, you’ll find that races are divided into age groups. This means that you will be competing alongside other male or female triathletes who fall into the same age band as you, with the exception of triathletes who fall into the separate elite category.

As we’ve mentioned already, a Full Ironman is tough going, so probably a little over-ambitious for a complete beginner, however, if you’ve already got an Olympic or Half Ironman under your belt, a Full Ironman would be a great next challenge for you.
