Ironman triathlons

Ironman. The name sets exactly the right tone for these gruelling triathlons, whether they're officially related to the Ironman brand or just follow the same format. Also known as 'full distance' triathlons, these are serious events that need dedicated training and preparation to complete, let alone to set a competitive time.

Incorporating a 2.4 mile (3.8K) swim, 112 mile (180K) cycle and 26.2 (42.2K) run, Ironman triathlons don't hold back on challenging their competitors. Take into account any ascent on the bike and run portions, as well as the rigours of cold open water swimming, and it's easy to see why many entrants do not make it to the finish line.

While some ultra triathlons include distances greater than the full distance, Ironman triathlons are still regarded as the peak of this sport, with amateurs and professional athletes alike travelling around the world to complete events and earn the right to carry the M-Dot tattoo.

It goes without saying that these triathlons are not entry-level and should not be entered by beginners. One reason that many people are dissuaded from entering an event in the first place is the amount of training required, but with the right advice and bucketloads of dedication, it is completely possible to enter and finish an Ironman triathlon.

See you on the start line - we'll be to the side cheering.
