How Long Is A Triathlon?

“ How long is a triathlon ?” is one of the first questions on people’s minds when considering taking up this sport. Well, the answer is: it depends!

The beauty of triathlon is that there is a race for everyone – from a supersprint with the swim in a pool and the run only 2km for a beginner triathlete, through to the ultimate challenge of a 226 kilometre Ironman.

And no matter how fit (or unfit) you are, with a little training, you will be able to complete a race.

There are also variations on the traditional triathlon, including duathlons (run, bike, run), aquathlons (swim, run) and off-road triathlons - commonly called an Xterra - which involves swimming, mountain biking and trail running.

If you are the sort of person to get a bit obsessed with your times, then bear in mind that races are not always measured out to the exact distance.

This includes elite races – yes, sometimes those amazing 10k run times are too good to be true!

So there really is something for everyone. The standard triathlon and ironman distances are listed below.
