The Ironman is a type of Triathlon discipline where you swim 3800 metres, do a bicycle ride of 180 kilometres and run a full marathon, which amounts to precisely 42.195 kilomtres.

And that is not enough. You have to do it all on time, the individual parts as well as the whole thing that has to be done within seventeen hours or less.

It goes without saying you need to be very fit to complete and Ironman – hence the name. But what exactly does it take and how much do you need to train?

Keynote speakers on Ironman take a closer look at the tough challenge and try to answer some of these questions.
